锰的三元络合物光度分析报导不多。对于锰的三元混配络合物与表面活性剂所形成的四元络合物的研究尚未见报导。我们研究了锰(Ⅱ)与铬天青S (CAS),1,10-邻菲啰啉(phen)、溴化十六烷基三甲基铵(CTMAB)四元体系的显色反应及络合物组成,并应用于测定矿石中的微量锰。实验部分 1.主要试剂和仪器: (1)锰标准溶液:用光谱纯MnSO_4·H_2O配制成每毫升含100μgMn,使用时再稀释。 (2)CAS溶液:2×10~(-3)M。(3)phen溶液:0.5％(含25％乙醇)。(4)CTMAB溶液:5×10~(-3)M(含5％乙醇)。(5)缓冲溶液:pH10.5,用0.05M硼砂和0.1MNaOH配制。
Manganese ternary complex photometric analysis reported little. No reports have been reported on the quaternary complexes formed by the ternary complex complexes of manganese and surfactants. We have studied the color reaction of Mn (Ⅱ) with chrome azure S (CAS), 1,10-phenanthroline (phen) and cetyltrimethylammonium bromide (CTMAB) Composition, and applied to the determination of trace manganese ore. Experimental Part 1. Main Reagents and Instruments: (1) Manganese standard solution: Prepare 100μg Mn per milliliter with pure MnSO 4 · H 2 O, and dilute it when used. (2) CAS solution: 2 × 10 ~ (-3) M. (3) phen solution: 0.5% (containing 25% ethanol). (4) CTMAB solution: 5 × 10 -3 M (containing 5% ethanol). (5) Buffer solution: pH 10.5, formulated with 0.05M borax and 0.1M NaOH.
