Abstract�� The process for obtaining potassium nitrate from potassium chloride and nitric acid produces much waste acid containing potassium salt. Waste acid is disposal the key problem to industrialize this process. In this paper, producing active white carbon black by using this waste acid has been studied. This new process can solve the problem of waste disposal and reduce the production cost of active white carbon black.

Keywords�� s:active white carbon black waste acid potassium nitrate
