本工作的目的是介绍硝酸盐选择性离子交换树脂Purolite A 520 E去除硝酸盐的实验结果。确定了去除硝酸盐的最佳树脂用量。吸附等温线已被Langmuir和Dubininin-Radushkevich（DR）方程模拟。用柱法研究了Purolite A 520 E强碱性阴离子交换树脂对硝酸盐的去除效果。氯离子和硫酸根离子的存在影响树脂对硝酸根的穿透能力。硝酸盐也被有效地从地下水中去除。吸附在Purolite A 520 E上的硝酸盐用0.6 M NaCl定量洗脱。(c)2006 Elsevier B. V.保留所有权利。
The aim of this work is to present experimental results on the removal of nitrate by nitrate selective ion exchange resin, Purolite A 520E. The resin dose as the optimum condition for nitrate removal was determined. Adsorption isotherm has been modelled by Langmuir and Dubinin-Radushkevich (DR) equations. Nitrate removal by strong base anion exchange resin Purolite A 520E was also carried out with column method. The existence of chloride and sulfate ions influenced the breakthrough capacity of the resin for nitrate. Nitrate was also effectively removed from the ground water. The nitrate sorbed on Purolite A 520E was quantitatively eluted with 0.6 M NaCl. (c) 2006 Elsevier B.V. All rights reserved.
