中文摘要：通过批量吸附研究测试来评价各种低成本材料—像高岭石、膨润土、粉煤灰、褐煤和尼尔马力种子从水中去除氟的能力。同时研究确定最佳的操作系统参数，例如接触时间、pH、吸附剂的剂量和大小等。目前的研究表明像尼尔马力种子和褐煤并不有效（去除率仅6-8%），而高岭石的去除率略高（18.2%）。粉煤灰和膨润土展现出最高的去除率，在最佳的系统条件下分别可达38%和46%。对粉煤灰进行化学预处理并未提高水中氟的去除率。

Abstract：Various low-cost materials like kaolinite, bentonite, charfines, lignite and nirmali seedswere investigated to assess their capacityfor removal of fluorides from water by batch adsorption studies.Studies were also conducted to determine optimum operating systemparameters; such as contact time, pH, dose and size of the adsorbent. Present study has indicated that materials like nirmaliseeds and lignite are not effective (removal 6 to 8%); whereas removal by kaolinite clay was slightly higher (18.2%). Charfines andbentonite exhibited highest removal capacity of 38 and 46%, respectively, at optimum system conditions. Chemical pre-treatmentof charfines did not result in enhanced removal of fluoride from water.
