1/11/2020, · In the hydrochloric ,acid,/nitric ,acid, system, Pt/Pd can form the corresponding xanthate precipitate with xanthate. The xanthate solution is stable in the pH range of 6.5–7.5, but it partially decomposes into carbon disulfide and alcohol in acidic solutions (Cheng and Luo, 2016). The reaction equation is as follows: (88) ROCSS − + H + = CS 2 + ROH
