中文摘要:
      在硫酸介质和沸水浴中,As(Ⅴ)与钼酸铵作用,然后被抗坏血酸还原生成砷钼蓝络合物,而As(Ⅲ)在同样条件下则不显色。在波长620nm处测定溶液的吸光度。从而建立了砷钼蓝法测定某含金砷多金属矿处理过程中砷的含量及其价态的分析方法。测定结果对冶金工艺设计有一定的指导意义。
英文摘要:
      In H2SO4 and boiling watet bath,As(Ⅴ) contacts with ammonium molybdate, followed by treatment with ascorbic acid to form arsenomolybdate blue complex,in the same condition,the color reaction of As(Ⅲ) with ammonium molybdate is almost not found.Thus the absorbance of the solution can be measured at wavelength of 640 nm.A method has been established for the determination of arsenic and its valence in the treatment of a gold and arsenic containing polymetallic ore by arseno-molybdenum blue method.The results?has?active?guidance?meaning to the design of process metallurgy.
