METHOD FOR PREPARING POTASSIUM ACETATE USING A POTASSIUM HYDROXIDE WASTE SOLUTION CONTAINING SILICON COMPOUND AND A WASTE SOLUTION CONTAINING ACETIC ACID

摘要

According to the present invention , nitric acid , acetic acid , phosphoric acid -containing waste liquid by heating the liquid mixture of acetic acid and nitric acid the gain , that is a mixture of potassium hydroxide waste liquid silicon compound contained therein , and then heated to remove the acetic acid solution , and then separated by removing the acid solution was allowed to react by mixing a potassium hydroxide -containing waste liquid is a silicon compound and a silicate potassium acetate can get . ;
