| Abstract: | The calcification process for synthetic of oxalic acid was compared to the lead involved process which produces huge amount of lead-contented wastewater.Substantial data have been collected to show that the lead-contented wastewater is very difficult to be treated and thus brings considerate pollution to the environment.This problem can be solved by using the calcification process instead of lead-process,and the product quality will be improved as well. |
