摘要
在强碱性溶液介质中,非离子表面活性剂Tween-80存在下,镍与丁二酮肟(H2DX)形成红棕色络合物,最大吸收波长位于480nm,镍量在2—20μg/25mL范围内服从比耳定律,表观摩尔吸光系数为1.88×104L.mol-1.cm-1,测定废旧电池、污泥中的镍,结果令人满意。
In alkali medium with non-ionic surfactant tween-80, nickel reacts with dimethylglyoximes and forms brown-red complex compound with the apparent molar absorptivity at 480nm of 1.88 × 10^4L · mol^-1 · cm^-1. Beer＇s law is obeyed in the range of 2-20μg nickel per 25mL. This method was used for the determination of nickel in mud and waste battery. The results are satisfactory.
