Abstract

The removal of boron by Donnan dialysis from aqueous solutions has been studied according to response surface methodology (RSM). First, a preliminary study was performed with two membranes (AFN and ACS) in order to determine the experimental field based on different parameters, such as the pH of the feed compartment, the concentration of counter-ions in the receiver compartment, and the concentration of boron in the feed compartment. The best removal rate of boron was 75% with the AFN membrane, but only 48% with the ACS membrane. Then, a full-factor design was developed to determine the influence of these parameters and their interactions on the removal of boron by Donnan dialysis. The pH of the feed compartment was found to be the most important parameter. The RSM was applied according to the Doehlert model to determine the optimum conditions ([B] = 66 mg/L, pH = 11.6 and [Cl] = 0.5 mol/L) leading to 88.8% of boron removal with an AFN membrane. The use of the RSM can be considered a good solution to determine the optimum condition for 13.8% compared to the traditional "one-at-a-time" method.

摘要

根据响应面法（RSM）研究了通过唐南透析从水溶液中去除硼的情况。首先，使用两种膜（AFN和ACS）进行了初步研究，以便根据不同参数确定实验范围，这些参数包括进料隔室的pH值、接收隔室中抗衡离子的浓度以及进料隔室中硼的浓度。使用AFN膜时硼的最佳去除率为75%，而使用ACS膜时仅为48%。然后，开展了全因子设计，以确定这些参数及其相互作用对通过唐南透析去除硼的影响。发现进料隔室的pH值是最重要的参数。根据Doehlert模型应用响应面法来确定最佳条件（[B]=66mg/L，pH=11.6和[Cl]=0.5mol/L），使用AFN膜时硼的去除率可达88.8%。与传统的“一次一个变量”方法相比，使用响应面法可被视为确定最佳条件的一种很好的解决方案，硼去除率提高了13.8%。
