本文从卫生学角度出发,对安徽省狮子山铜矿区通常的稻田土壤标本和受铜不同程度污染的稻田土壤标本,用七种萃取剂[0.05N HCl、0.1 N HCl、3 N HCl、0.05M EDTA、DTPA、1 N NH_4OAc(pH7.0)和1 N NH_4OAc(pH4.8)]进行了萃取铜的相对有效性的分析比较。结果筛选出了一种最为适用的有效铜萃取
In this paper, from the point of view of hygiene, the paddy field soil samples in paddy field of Shizishan copper mine in Anhui Province and paddy soil samples polluted by different levels of copper were extracted with seven extractants [0.05N HCl, 0.1 N HCl, 3 N HCl, 0.05 M EDTA, DTPA, 1 N NH 4 OAc (pH 7.0) and 1 N NH 4 OAc (pH 4.8)] were compared for their relative effectiveness. The results screened out one of the most effective copper extraction available
