| titleOfInvention | A kind of method for removing arsenic in nickel sulfate solution containing arsenic |
| abstract | A kind of method for removing arsenic in nickel sulfate solution containing arsenic, according to arsenic:The ratio between molal quantity of tungsten or molybdenum is 1:9 12 add in sodium tungstate or sodium molybdate into nickel sulfate solution containing arsenic (pH≤2), and reaction obtains solution containing heteropoly acid；It is then injected into the exchange column equipped with large aperture resin anion (R.A.), obtains liquid after ion exchange and the large aperture resin anion (R.A.) after absorption heteropoly acid.The raw material used in whole process of the present invention can be recycled.And tungstate radicle or molybdenum acid ion lose small (less than 0.5%), after the exchange finally obtained in liquid arsenic content in 0.5ppm hereinafter, complying fully with demand of industrial production. |
