摘要
乙炔中磷化氢测定的仲裁法采用比色法,用氯化亚锡甘油溶液替代氯化亚锡盐酸溶液后,延长了氯化亚锡溶液的保存期限,使乙炔中磷化氢的测定更加方便。
The arbitration determination method of phosphine was colorimetry.In the actual determination,tin chloride solution was replaced with tin chloride glycerol solution,and the storage life was extended,the determination was rapid and the analysis cost was reduced.
