EFFECTS OF MODIFICATION AND CALCINATION CONDITIONS ON THE ADSORPTION PERFORMANCE OF RED MUD FOR LOW-CONCENTRATION FORMALDEHYDE IN AIR
2013
Environment Protection Engineering
unpublished
The effects of modification and calcination conditions on the performance of red mud (RM) to absorb low-concentration formaldehyde in air were investigated using a fixed-bed flow reactor. The results show that the adsorption of RM for formaldehyde increases upon decreasing calcination temperature , with the optimum calcination temperature of 300 °C. H 2 O 2 modification can improve the adsorption performance, with the optimum modification concentration at 20 wt. %. Pore structure analysis
