Therefore, for the first time we decided to evaluate the effectiveness of grape anthocyanins and ascorbic acid in water treatment, investigating their toxic effects by the most informative and simple method in the modern world - biotesting, as well as their antimicrobial and antioxidant effects. As a result of this work, it was found that water samples with ascorbic acid at concentrations of 40 and 100 mg / dm3 did not show acute and chronic toxic effects on aquatic organisms and onions. Also, these concentrations did not cause nuclear abnormalities in fish blood cells and did not show a cytotoxic effect. It is shown that the bactericidal and fungicidal action of anthocyanins and ascorbic acid is due to the pH and their antioxidant action. The pH and antioxidant action of ascorbic acid are more stable in the aqueous medium than in anthocyanins, so ascorbic acid showed a better disinfectant effect. The culture of C. albicans is disinfected worse under the action of both disinfectants. It is shown that grape anthocyanins do not show antioxidant action against nitrates, and ascorbic acid is able to neutralize nitrates in small quantities. It was found that the concentration of grape anthocyanins 20 mg/dm3 neutralizes only up to 2 mg/dm3 of active chlorine, the concentration of 50 mg/dm3 neutralizes up to 3 mg/dm3 of active chlorine. It was found that ascorbic acid in a concentration of only 40 mg/dm3 is able to neutralize 10 mg/dm3 of active chlorine, with the formation of micro-quantities of non-toxic, harmless to the human body, without the formation of additional chlorinated organic molecules. Based on the obtained results, it is proposed to use ascorbic acid in concentrations of 40 and 100 mg/dm3 for the purification of tap water.
