洛带垃圾填埋场周边水中铬污染特性研究

Features Research on Chromium Pollution of Water around Luodai Landfill

采用柱层析—可见分光光度法测定洛带垃圾场周边水中铬的含量.以2 mg/mL二苯碳酰二肼(DPCI)作为显色剂,于540 nm波长处测定吸光度.结果显示:大部分水样中的铬含量超过生活饮用水水质标准.此法简便、准确、稳定,重现性好且成本较低.

Column chromatography-photometry was used to determine content of chromium contained in landfill surrounding of Luodai.Taking 2 mg/ml DPCI ascolor-display reagent,it was put at 540nm wavelengths to determine absorbency.Results show that：most water chrome content is over the quality standard that the drinking water contains.This method is simple,accurate and stable,reproducible and of low cost.
