The experiments show that this process is suitable for the treatment of sorbic acid manufacturing wastewater. About 98% sorbic acid and 50% CODcr were removed under optimal operating conditions, and 70% of sorbic acid in sorbic acid manufacturing wastewater was reclaimed. This process makes it possible to recover valuable materials from the wastewater and to improve the quality of effluent water.展开更多

A holistic approach in- cluding normal XRD, FT-IR, and UV-Vis measurements and simultaneous TG/DTA/MS and in situ HT-XRD techniques was employed to explore the supramolecular intercalation structure and the thermal decomposition properties of as-synthesized SA-ZnAl-LDHs material.展开更多
