Study on regeneration of waste powder activated carbon through pyrolysis and its adsorption capacity of phosphorus

The regeneration of WPAC through pyrolysis and its adsorption capacity of phosphorus were studied. The optimum conditions for WPAC regeneration were 650 °C and 2 h which resulted in a recovery of BET surface and total pore volume with a value of 1161.4 m(2)/g and 1.2176 m(3)/g. WPAC had a maximum PO...

description The regeneration of WPAC through pyrolysis and its adsorption capacity of phosphorus were studied. The optimum conditions for WPAC regeneration were 650 °C and 2 h which resulted in a recovery of BET surface and total pore volume with a value of 1161.4 m(2)/g and 1.2176 m(3)/g. WPAC had a maximum PO(4)(3−)-P adsorption capacity of 9.65 mg/g which was 48.93% of PAC, while RWPAC had a maximum PO(4)(3−)-P adsorption capacity of 15.31 mg/g which was 77.64% of PAC. The kinetic analysis revealed that Langmuir model could well describe the adsorption process of PAC, WPAC and RWPAC on PO(4)(3−)-P and the PO(4)(3−)-P adsorption followed the pseudo-second-order model.
