摘要:

重量法测定氰化亚金钾中的金具有经济、简便和实用的特点。氰化亚金钾在酸性溶液中加热使金析出,经冷却、过滤、洗涤、灼烧后称重,由金折算成氰化亚金钾的系数可计算氰化亚金钾的金含量。此重量法适用于化学试剂氰化亚金钾金含量测定,有利于提高分析结果的准确性。

关键词: 氰化亚金钾, 含金量, 重量法

Abstract:

Determination of gold in inferior gold potassium of cyaniding by the gravimetric method is economic,simple and practica1.We get the gold by heating the inferior gold potassium of cyaniding in acidic solution,cooling,fihe— ring,washing and weighing,we can calculate the determination of gold in inferior gold potassium of cyaniding.The gravimetric method is be beneficial to elevate the accuracy of analysis results.

Key words: Inferior gold potassium of cyaniding, Determ ination of gold, Gravimetric method
