  Abstract

In this study, PSf-Al(OH)3 beads were prepared by immobilizating aluminum hydroxide Al(OH)3 with polysulfone (PSf). The removal experiments of the fluoride ions by PSf-Al(OH)3 beads were conducted batchwise and the parameters such as pH, initial fluoride concentration, and coexisting ions were investigated. The maximum removal capacity obtained from Langmuir isotherm was 52.4 mg/g and the optimum pH region of fluoride ions was in the range of 4 to 10. The removal process of fluoride ions by PSf-Al(OH)3 beads was found to be controlled by both external mass transfer at the earlier stage followed by internal diffusion at the later stage. The presence of coexisting anions such as HCO3-, SO42-, NO3-, and Cl- had a negative effect on removal of fluoride ions by PSf-Al(OH)3 beads.
