在用间接碘量法测定有效氯时,一般是用醋酸调节溶液酸度。但因测定次数多,醋酸耗量大,价格高,所以药品费用高。针对这个问题,我们做了如下试验:以强酸(硫酸)代替弱酸(冰醋酸)来调节溶液酸度。通过多次对照试验,结果表明,两种方法测定结果完全一致。从理论

In the determination of available chlorine with indirect iodine method, the acidity of the solution is generally adjusted with acetic acid. However, the determination of the number of large, acetic acid consumption, high prices, high drug costs. In response to this problem, we did the following experiment: Strong acid (sulfuric acid) instead of weak acid (glacial acetic acid) to adjust the solution acidity. Through multiple control experiments, the results show that the two methods are exactly the same measurement results. From theory
