摘要

Due to the harmful disinfection by-product which comes from the chlorine disinfectants, people are exploring new disinfectants with higher safety in recent years.Tea polyphenols are some kind of pure natural nontoxic organics with disinfection effect.However, the water chromaticity has yet to meet drinking water standards using tea polyphenols as disinfectant for drinking water.Anthocyanins are known to be natural pigments containing in tea polyphenols, the influence of the water chroma caused by anthocyanins in the disinfection process was explored.Furthermore, to understand the effect of anthocyanins on the antibacterial performance of the tea polyphenols, the concentration of anthocyanins and species in tea polyphenols were detected by pH differential method and high performance liquid chromatography (HPLC),it took the anthocyanin standard for disinfection test.The results indicated that most of anthocyanins in tea polyphenols existed in form of glycosides.The concentration of anthocyanins which accounted for 14.3％of chromaticity value in the tea polyphenols, was only 0.01 1％.Despite the bacteriostasis ability shown by anthocyanins, its effect on the antibacterial performance of tea polyphenols hasn't be seen due to very low concentration.Theoretically, the chromaticity caused by anthocyanins could be easily eliminated by some method that depend on the unstable character of glycosides.The removal of the anthocyanin from tea polyphenols doesn't affect the antibacterial performance of the tea polyphenols as disinfectant.
