摘要
本文研究了氯与碘酸银反应放出碘酸根,并使碘酸根在酸性条件下与碘离子反应产生碘,以可溶性淀粉显色,分光光度法测定水中微量氯的新方法,本法检出下限为2.0×10^(-5)molL^(-1)线性范围0.5～5×10^(-4)mol·L^(-1).应用于水中微量氯的测定,结果满意.
In this paper, the chloride reacts with silver iodate to give iodate and iodate reacts with iodidein slightly acidic solution to give iodine and starch soluble color.The spectrophotometric determination mierochlo ride.The detection limit of the method is 1. 0 × 10-5mol L-1 and the linear range is kept between 0. 5 ~ 5 × 10-4mo1. L-1. This method has been applied to the determination of microchloride in water with satisfactory results.
