摘要
采用王水(1+1)试溶解试样,于硫脲介质中用火焰原子吸收光谱法测定矿石中金,重点考查了活性炭富集金的实验条件。缩短了分析时间,消除了干扰元素对测定的影响,相对标准偏差为0.85%(n=7),平均回收率为98.11%～101.05%。
Used aqua regia（1＋1） to dissolve sample,measured gold by using the spectrum method of flames atom absorption in thiourea solution.Mainly examined experiment condition in accumulate gold with charcoal.Shortened the analysis time,eliminated influence of a large number of disturbance elements.The RSD（%） was 0.85（n=7） and recovery of 98.11%~101.05%.
