摘要
建立用微波消解技术处理城市生活垃圾样品,以自动电位滴定法测定城市生活垃圾中的氯含量。讨论微波消解条件、自动电位滴定仪工作参数、酸度及干扰情况,并对城市生活垃圾中的氯含量进行测定,相对标准偏差〈2.5%,回收率为97%~102.5%。
A method was established to determine chloride content in household waste by automatic potentimetric titrimetry,the samples of household waste were pretreated by microwave digesting technique.The factors including of conditions of microwave digestion,work parameters of automatic potentimetric titrator,pH and disruptors were studied.The chloride content in the household waste was determined.The result showed that the relative standard deviation was lower than 2.5%,the recovery rate was 97%~102.5%.
