检测贮存温度、浓度和时间对3种不同商标含次氯酸钠的家庭用漂白剂的影响,并比较这些漂白剂的稳定性。 作者采用的3种含次氯酸钠的家庭用漂白剂为 Hypo,Clorox和Domex。它们的生产期相同,在生产后2周从制造商处获得。每种漂白剂依含有效氯(％)浓度和贮存温度都分4组即5±0.02(％),24℃;0.5±0.002,24℃,5±0.02,4℃;0.5±0.002,4℃。12组液体都避光、密封在玻瓶中,检测时间从起始到15d,以后各为22,29,36,43,60,95,131,177和200d。并在起 The effect of storage temperature, concentration and time on the household bleach containing 3 sodium hypochlorite in 3 different trademarks was tested and the stability of these bleaches was compared. The three sodium hypochlorite-containing home bleaches used by the author are Hypo, Clorox and Domex. They have the same production period and are obtained from the manufacturer two weeks after production. Each bleach was divided into 4 groups of 5 ± 0.02 (%), 24 ° C; 0.5 ± 0.002, 24 ° C, 5 ± 0.02, 4 ° C; 0.5 ± 0.002 at 4 ° C, depending on the concentration of available chlorine (%) and storage temperature . The 12 groups of liquids were protected from light and sealed in glass bottles. The detection time was 22, 29, 36, 43, 60, 95, 131, 177 and 200d respectively from the beginning to 15d. And from there
