摘　　要：用HCA-100标准消解器进行快速加热,控制加热时间,并设有风冷加水冷的冷凝回流,同时减小加药体积,快速消解加热测定了地表水的高锰酸盐指数.该方法缩短了实验时间,短时快速测定出高锰酸盐指数,确定了稀释倍数,避免了多次反复稀释,提高了工作效率,适应了日益繁重的水质监测工作要求.Rapid digestion heating method of the potassium permanganate index in surface water uses the HCA-100 standard digestion device to heat rapidly,the heating time is controlled, a wind cooling and water cooling condenser reflux is provided, and at the same time the dosing volume is reduced simultaneously. This method can reduce the experiment time and measure the reference value in a short time. It also determines the dilution ratio so that can avoid the repeated dilution and improve the efficiency to order to adapt the increasingly heavy water monitoring requirements.
