摘要
实验研究了提钒废水中硫酸钠和氯化钠对重量法测定水中悬浮物的干扰,讨论了洗涤法对可溶性盐干扰的不足。提出用双滤法消除硫酸钠和氯化钠的干扰,通过实验结果表明,该方法适用于提钒废水悬浮物的测定,其它含可溶性盐的水的悬浮物测定也可采用此方法。该方法不改变原有测定条件,具有较高的准确性。
.The experiment studies the interference of vanadium extraction wastewater sodium sulfate and sodium chloride on the gravimetric determination of suspended solids in water, discusses the inadequate washing method of soluble salts interference, and proposed using the double filtration method to eliminate the interference of sodium sulfate and sodium chloride.The experimental results' show that the method is applicable to the determination of vanadium ex- traction wastewater suspended solids,and it can also be used in other Determination of suspended solids in water contain- ing a soluble salt. This method does not change the original measurement conditions with hiah accuracy.
