Study and Application of Determining Ni (Ⅱ) by a New Reagent Morpholine Dithiocarbamate Morpholine Chloride

YANG Shui\|ping, HUANG De\|chao, YANG Chuo (Department of Chemistry, Fuzhou Normal College, Fuzhou, JX 344000, China)  
The conditions of the color reaction of morpholine dithiocarbamate morpholine chloride(MDMC) with Ni (Ⅱ) are studied in this paper. The yellow complex is formed when pH value is at 9.0. The maximum absorption peak is at 400 nm and the apparent molar absorption coefficient is 1.42×10\+4 L·mol\+\{-1\}·cm\+\{-1\} . The method is applied to determine trace Ni (Ⅱ) in synthetical water sample with satisfactory results.
