【摘要】 MoO（SCN）₅离子与染料罗丹明B（RhB）反应,生成蓝色三元络合物MoO（SCN）₅（RhB）₂,在600 nm有强吸收,依此原理开发钼自动监测仪。检出限达到0.042 2 mg/L,精密度为6.19%～9.44%,加标回收率为82.4%～116%,质控图中所有数据均未超出x±3s区间内,与测定钼的标准方法具有可比性。该仪器应用于某地表水应急事件中,其监测数据有效指导事故处理。更多还原

【Abstract】 The reaction of the molybdenum oxypentathiocyanate ion with the dyestuff Rhodamine B（Rhb） produces the ternary complex, MoO（SCN）₃（Rhb）₂.The ternary complex absorbs strongly at 600 nm, forming the basis why the automatic water quality monitoring instrument for molybdenum can be made.The detection limit is 0.042 2 mg/L, the precision is 6.19%～9.44%, the recovery rate is 82.4% to 116%, and all of the data in the quality control profile did not exceed the range of x±3s.The instrument is comparable to the standard method for determining Molybdenum.In a surface water accident emergency, the data determined by the instrument effectively guided the accident handling.更多还原
