摘要：

The hydrogen fluoride (HF) and fluoride ion (F) adsorption potentials of a water treatment sludge were investigated in a batch mode as a function of pH, contact time, initial fluoride concentrations, and other co-existing anions. The maximum removal of total fluoride was apparently observed at pH 5.1, whereas HF or F- adsorptions showed nearly 100% in pH range from 2.2 to 4.3. The HF or F- adsorption by the water treatment sludge has occurred rapidly during the initial 5-60 min and thereafter slowly increased until 48h. The other anions such as SO12-, NO3- and Cl have not adversely affected on extent of HF or F adsorption by the water treatment sludge.
