| Abstract: | The influence of several factors in producing polyferric sulfate with NaNO2 as catalyst has been studied .The results show that the optimum ratio of [SO2-4] : [Fe]total is 1.40 - 1.45 :1 .The optimum speed of adding NaNO2 to the reacting sytsem is 30 g L-1 h -1. Reaction rate is increased by 44% with oxygen than air. Stabillity of the product can be improved greatly by the addition of agent MS. The COD removal ratio is 92% and decoloring ratio is over 98.8% when the product is used to treat printing - dyeing waste water. |
