재음다적제불기술중,흡부법시최상용적방법.각취당이기무독、역강해、렴개역득등우점,성위제비신형제불제적이상재료.종술료교련각취당、최갑기각취당、각취당/희토배합물、과도금속개성각취당등연생물적제비방법、궤리급기대수중불리자적흡부효과,병대금후적연구방향진행료전망.
Among all the treatments proposed,adsorption technique is the most widely accepted and also an applied method for the removal of fluoride from drinking water.Chitosan is an ideal material for preparation of fluoride removal agents based on its excellent properties such as non-toxicity,biodegradability and low-cost.The preparation methods,mechanisms and adsorption effects of several chitosan derivatives including cross-linking,carboxyl methylation and chitosan metal complexa are reviewed.And the future research directions are also put forward.
