| Abstract: | In order to decline the influence of deleterious impurity in WPA on phosphorus chemical product and to increase the added value of the products made from WPA, the oxidation-absorption-deposition purification technology for the deeolorization and iron removal of WPA are studied. Results show that by adopting oxidation-absorption-deposition treatment to treat the WPA, the decolorzation rate is of 92.3%, the iron content is decreased effectively. |
