<p>塩素系漂白剤は保管中に分解し濃度が低下するため，使用前に濃度を知ることが望ましい．そこで，酸化コバルトを触媒として，次亜塩素酸ナトリウムを分解し，発生する酸素量V(mmol)を測定し，濃度H(%)との関係を求めた．両者には比例関係が認められ，V=6.40H+0.03で表される一次式(相関係数0.999，定量下限値2.8×10^-2mmol)を得た．測定値の信頼性は0.112±0.002%(mean±SD,n=3)，変動係数0.018,標準誤差0.001%であった．これを検量線として用いて，市販塩素系漂白剤の有効塩素量を定量した．開封直後のものは5.2%で,古いものほど分解が進み,濃度が低下していることが分かった．酸化コバルトを触媒に用いた本法の反応機構を検討した結果,実測値ならびに理論式とよく一致し,濃度決定に適用可能であることが分かった.</p>

In a previous study, it was determined that nonionic surfactants could be removed from wastewater using the typical soil. In this report, the recovery of nonionic surfactants was examined with the purpose of reusing the removed surfactants. It was found that a packed bed of soil employed with the nonionic surfactants and the use of alcohol as the recovery agent was most effective. In the case of polyoxyethylenenonylphenylether NP10 (50 ppm), 50 vol% i-PrOH was found to be the most effective for the recovery process. This resulted in a recovery rate of 100%. The following recovery rate was recorded in descending order of i-PrOH>t-BuOH>n-PrOH, EtOH>MeOH. Also, the maximum recovery value resulted between each of the 5 alcohol concentration and their respective recovery rates. The recovery rate of the nonionic surfactants of a low concentration was decreased. In addition, the recovery rate of nonionic surfactants decreased as the mole numbers of the added ethyleneoxide units increased for the nonionic surfactants NP10, NP15 and NP20.

The ability of a typical soil to remove nonionic surfactants from wastewater was investigated. A packed bed using the above soil, with suction filtering of Polyoxyethylenenonylphenylether (NP10,15,20) solution through the packed bed, was prepared. We found that the removal efficiency decreased as the concentration of the NP10 solution is increased and that the Freundlich equation could be used to describe the relationship between the concentration and the removal efficiency in the concentration range of 20-200 ppm. In addition, the removal efficiency tended to decrease as the mole number of added ethyleneoxide (EO) units is increased. This method was found to have a high removal efficiency with regard to wastewater including these solutions of such low concentration that would be discharged into the environment.

It is often required to compare the depth of colors of solid matters in homemaking studies. The colorimeter is widely used, but it is difficult to use it in school education for financial reasons. So, usually a visual comparison is made and the results are recorded subjectively. Because of the reasons mentioned above, a trial production of a simple colorimeter was attempted. Also, we studied the relation of the concentration of detergent to detergency, and the concentration of bleaching agent to bleaching efficiency; we also researched how to prevent cut ends of apples from browning, using the trial apparatus. As a result of these studies, a close agreement between experimental results measured by this trial colorimeter and results measured by the colorimeter on sale were obtained. The availability of the trial colorimeter was thus confirmed.

The hosehold bleaching agent, sodium hypochlorite, has been employed for bleaching, sterilization of drains and toilets, and cleaning sinks. For safe and effective use, particular attention should be given to the concentration of the agent, because the available concentration often decreases easily. According to the Japanese Industrial Standard, the concentration of sodium hypochlorite is determined titrimetrically with sodium thiosulfate and represented by the "concentration of available chlorine H." Titrimetric methods have required a variety of agents and have been accompanied by a difficulty in detecting the end-point of the titration. In this study, a method for measuring the available concentration was developed through the volumetric analysis of oxygen gas produced from the reaction when sodium hypochlorite and hydrogen peroxide are mixed. The method offered much saving in time, cost, and complexity. An analysis of the relationship between the amount of the oxygen gas and the concentration of available chlorine H by the JIS method showed a correlation of 0.998, indicating that this method is very useful for measuring the concentration of sodium hypochlorite in solutions. This method should enable the apparent rate constant of the reaction to be determined when the amount of the produced oxygen gas is measured at regular time intervals.

In order to create an awareness in school of the association between science and technology with daily life, daily necessities were employed as learning subjects. This study created such an awareness in high school students by using disposable diapers as an example of a daily necessity. In this lesson, each student was first asked to indicate a preference for either hydrophilic or hydrophobic lining for the diaper, and then to prepare two diapers using hydrophilic or hydrophobic lining,water-absorbent padding and backing.A Iarge percentage of studentsexpressed the common assumption that since hydrophilic materials were suitable for fabrics contacting the skin they were also suitable for the lining of diapers. However, after a measured quantity of water was poured onto the two diapers and the two linings were compared by touch, the students recognised their misconception. They also observed that the water absorption rate of commercial diapers was much faster than those of their own making, illustrating the absorption mechanism. Thus they learned that many aspects of science and technology taught in school, such as capillary action and super absorbent polymer to soak up large amounts of water, were employed in the production of disposable diapers which they had formerly regarded simply as paper and cotton pulp. This research should enable us to recognize the need to adopt as learning subjects objects in the daily livers of the learners.

The object of this study is the development and/or application of teaching materials to support integrated study from the standpoint of natural science.A trial gas-buret was used for volumetric analysis of carbon dioxide formed as a reaction product of sodium carbonate and a large excess of hydrochloric acid.From the results of this teaching material, the following three evidences were confirmed;(1)The volume of carbon dioxide is strictly proportional to the weight of sodium carbonate, and a calibration curve on each compound is easily obtained.(2)Molecular weight of sodium carbonate(105.0)obtained from a slope of a calibration curve is in fair agreement with that of the calculated value(105.99).(3)In six kinds of weak alescent synthetic detergents and four kinds of soaps, the content of sodium carbonate were determined.In detergents, the content of sodium carbonate were shown to be in the range of 8.16-39.3 Wt%, while in soaps it was in the range of 2.15-33.3 Wt%.That is to say, the ratio of surfactants/carbonate in these samples were not constant.It may be concluded that a trial gas-buret could be used, as teaching material, not only for acquiring of basic knowlege but also for creating and improving applications in daily life.
