ABSTRACT
ve To explore the methods for sanitary safety test of water purifier. Methods The water purifiers using active carbon, KDF and molecular sieve as absorptive materials and hollow fibers as filter materials were collected for sanitary safety test. The water purifiers were irrigated by pure water continuously for 15, 30, 45 and 60 min respectively first, and then were immersed continuously for 24 h by pure water, the variations of turbid-ity, pH value, total dissolved solid and chemical oxygen demand (COD), etc, of the immersing water were observed. The water purifiers were also irrigated continuously for 1 h at first, and then were immersed continuously for 5, 15, 24, 48, 72 h and 1 week by pure water respectively, in the end, the variations of those 4 sanitary indexes mentioned above were also detected. Results Significant differences were observed in those 4 indexes between the immering water samples obtained after 15 min-irrigation and 30 min-irrigation, 30 min-irrigation and 45 min-irrigation (P
