摘要
本实验通过样品前处理时进行双氧水处理,萃取过程采用混合萃取剂,消化过程采用硝酸、高氯酸、过氧化氢进行联合消解,能有效降低复杂基质中有机质在分光光度法分析水中钍的干扰,能有效提高分析结果的准确性。
The method can effectively reduce the interference of the organic fertilizer of thorium in water by using spectrophotometric method, and can effectively improve the accuracy of the analysis results through the sample pretreatment were treated with H2O2, the extraction process using mixed extractant, digestion using nitric acid and perchloric acid, hydrogen peroxide combined digestion.
