【摘要】 采用铬天菁S(CAS)、1,10邻菲啰啉(phen)、溴化十六烷基三甲基铵(CTMAB)与锰形成的四元络合物而显色的分光光度法测定滏阳河水中锰,检出限为0.02mg/L,加标回收率85.0%~96.0%,相对标准偏差为1.7%,同时对仪器及监测过程中应注意的问题提出建设性意见。更多还原

【Abstract】 Spectrophotometry,which colored by mixing CAS,PHEN,CTMAB and manganese,was adopted to determine manganese in water from the Fuyang River.The detected limit of this method was 0.002 mg/L,the mark-on recovery ranged from 85.0% to 96.0% and relative standard deviation was 1.7%,in addition,some advices of instrument and monitoring were posed in this paper.更多还原
