摘要
建立了催化光度法测定水中痕量银的方法,讨论了影响指示反应的最佳条件。结果表明,Ag浓度在0～40μg·L-1范围内符合比尔定律,用于水中的痕量银的测定,回收率均在97%以上,样品的相对标准偏差RSD<4%。
A catalytic spectrophotometry method for the determination of trace siliverin is proposed.The experimental results indicated that Beer′s law is obeyed in the concentration range from 0～40μg·L-1,It is used for the determination of trace siliverin in water.The recovery of themethod could reach 97%,the precision is below 4%.
