| Abstract: | This test studied an electrolyte for the diamond purification,and illuminated the influence of electrolyte components and process conditions on the weight increase of cathode as well as their mechanism.The experimental results showed that the optimum proportion and process parameters of the electrolyte were 15 g/L NH 4 Cl,30 g/L H 4 BO 3 ,25 g/L citric acid,15 g/L NaCl,10 g/L saccharine,current density was 8 A/dm2 and pH value was 5.The electrolyte could effectively decrease the electrolysis cost,and increase electrolysis purification efficiency. |
