Evidence Details
The removal efficiency of BPA first increased from 79.5% to 100% with the increase in solvothermal temperature from 180 °C to 220 °C, and then, it decreased to 89.8% with increase in solvothermal temperature to 240 °C.
Thus, the optimum conditions for preparing Bi2W0.25Mo0.75O6 were W/Mo molar ratio of 1:3, solvothermal temperature of 220 °C, solvothermal time of 5 min, precursor solution pH value of around 2.0, calcination temperature of 550 °C, and holding time of 120 min.
The inhibition rate of BPA was 93.6% ... and then further decreased to 63.3%, 50.5%, and 29.1% as photocatalytic times prolonged to 120, 150, and 240 min.
The removal efficiencies of BPA and total organic carbon were 96.2% and 87.1% at BPA concentration of 15 mg L−1 in 120 and 180 min, respectively.
