摘要
采用流动注射-分光光度法测定了环境水样中的硫化物。结果表明:其线性范围为0—0.6mg/L,方法的检出限为0.002mg/L,精密度RSD小于3%,对方法的回收率作了实验,所得结果在83.00%-95.33%之间。
Flow injection-spectrophotometry was used to determine the sulfide contents of the environmental water samples.The results showed that the linear range was 0—0.6mg/L and the detection limit was 0.002mg/L,the precision of the method was assessed,and the RSD was less than 3%.The recoveries of the method were 83.0%—95.33%.
