| Abstract: | Waste oxalic acid slime produces which with the production oxahc acid, which mainly contained steps of conversion by heating, dissolving in nitric acid and combination with sodium bichromate. Principle of preparation lead chromate from oxalic acid sludge was introduced. And effects of raw materials size, reaction temperature, reaction time and nitric acid dosage on the output and lead chromate content of the product were discussed in detail in this paper. |
