Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In those traditional ways of treating alkali weight reduction wastewater, the COD removal is greatly considered, while recovering the valuable resource according to the principles of sustainable development is less involved. In this study, the recovery of high pure TA from alkali weight-reduction has been researched by purified mother liquid with coagulation sedimentation. The characters of TA obtained was investigated by various methods, results has shown that the purity of TA was great improved in view of high recovery rate by coagulation sedimentation on conditions of pH 7.0-7.5 of wastewater and 300-400mg/l in quantity of Al2(SO4)3.18H2O, thermogravimetric analysis (TGA) spectrums proved this. Particle size analysis revealed the crystal size of recovered TA became greater, it contained few impurities. So coagulation-sedimentation by pretreatment is an effective method. The study is also very useful in recycling of PET and treating TA industrial wastewater.
