摘　　要：建立了TiO_2悬液催化净化实验系统,以去离子水为TiO_2载体,研究TiO_2悬液浓度、紫外光辐射照度、搅拌转速对室内空气中甲醛的去除效果。结果表明,在紫外光辐射照度18.5μW/cm^2、搅拌转速2 000 r/min,TiO_2悬液浓度2.5 g/L时,去除效果可达92.6%左右。A catalytic purification experiment system for TiO2 suspension was constructed,with deionized water as TiO2 carrier.The effects of different TiO2 suspension concentrations,different UV irradiances,and different magnetic stirrer rotation speeds on formaldehyde removal in indoor air were studied.The results show that the ultraviolet illuminance is 18.5μW/cm^2,the rotational speed of the magnetic stirrer rotor is 2 000 r/min,and the TiO2 suspension concentration is 2.5 g/L,the removal effect is good,and the effect can reach 92.6%.
