| Abstract: | Oxalic acid reclamation with lead sulfate in waste fluid from oxytertracycline was investigated, and its recoveries were determined by permaganate titration. The factors affecting the kinds of the recoveries of oxalic acid, such as the reaction time, the size of lead sulfate particles,inorganic acids and the concentration of the inorganic acid. In addition, different approaches recovering the used lead sulfate were also investigated. The results show that under the optimum conditions the recovery of oxalic acid is over 92 % and that the method is easy to operate and fit for the reclamation of oxalic acid in factory. |
