| Abstract: | Under UV irradiation,nanopowders Ti0_2 doped with Co which were prepared by sol-gel methods were used in the photocatalytic degradation of pentachlorophenol(PCP).The effects of degradation time,the amount of catalyst,and initial concentration on photocatalytic degradation of PCP were investigated.The initial concentration of the PCP solution was 0.01 mg/mL,pH 9.0-10,the amount of catalyst was 0.25 mg/mL,when degradation time was 150 min,the results indicated that the degradation rates of PCP is over 97%.Und... |
