摘要
采用不同浸提剂对固体废物中的硼进行浸提并用甲亚胺-H酸分光光度法进行分析,结果表明,pH=2.64±0.05的冰醋酸水溶液提取率最高。探讨了显色时间、pH值和金属离子等主要因素对测定的影响,选择了最佳实验条件,加标回收率在87%～103%之间。通过与ICP-AES方法比对结果表明,该方法准确可靠。
Various extraetants were applied for extraction of Boron from solid waste, and the obtained extracts were analyzed by Azomethine-H spetrophotometric melhod. The result showed that aqueous acetic acid with pH=2.64 ± 0.05 has better extraction rate than others. The effeets of developing time, plt value, metal ion and operating conditions were studied. The results gained under optimum condilion indicated that addition recovery was between 87%- 103%. Comparison with ICP-AES method shows that this method is reliable and the accmacy is suitable.
