一、钼的快速比色测定法的改进为了克服南方气温过高,乙醚蒸发太快和有机物对测定钼的干扰,经过几个月野外生产实践,改用乙醚一四氯化碳混合溶剂代替纯乙醚萃取,使轻溶剂变成重溶剂,解决了乙醚蒸发太快和有机质对测定钼的影响,效率较原方法有所提高。样品的分解:取0.5克样于溶解管中,加硝、硫混酸(HNO_3:H_2SO_3:H_2O=2:1:1)或硝、硫、硷
A molybdenum rapid colorimetric assay improvement In order to overcome the high temperature in the South, too fast evaporation of ether and organic compounds on the determination of molybdenum interference, after several months of field production practices, use ether instead of carbon tetrachloride mixed solvent instead of pure Ether extraction, the light solvent into a heavy solvent, to solve the ether too fast evaporation and organic matter on the determination of molybdenum, the efficiency of the original method has been improved. Sample Decomposition: Take 0.5 g sample in a dissolving tube and add nitric acid, sulfuric acid (HNO 3: H 2 SO 3: H 2 O = 2: 1: 1)
