摘要
对采用原子吸收次灵敏线测定低浸渣中锌量进行了研究。试验结果表明:在铁含量40%以内的情况下,锌含量小于30%时,采用原子吸收次灵敏线测定锌量,与氨水分离法结果相符,此方法简便快捷、准确、重现性好,适用于低浸渣中锌量的分析。加标回收率为:98.2%~101.8%。
The determination of zinc in low leaching residue by atomic absorption sub sensitive line was studied.The results show that:when the iron content is less than 40%and the zinc content is less than 30%,the determination of zinc content by atomic absorption sub sensitive line is consistent with that of ammonia water separation method.This method is simple,rapid,accurate and reproducible,Suitable for analysis of zinc content in low leaching residue.The recoveries were 98.2%~101.8%.
