A reliable LC-MS/MS method was developed and validated for the quantification of TDP-B and was successfully applied to a rat pharmacokinetic study.

Abstract. Acid dyes were more difficult to be removed by chemical coagulation method due to their solubility. The threshold of anaerobic of acid dyes as model dyes was investigated in this paper by the analysis of the degradation products were detected by GC-MS. High COD removal and low decolorization of the acid sye was obtained during the batch experiment. According to GC-MS results, the possible degradation pathway of the dye was proposed that the organic compounds remained in the supernatant were likely composed of soluble microbial products and the aromatic amines which was related to threshold of decolorization of the acid dye.
