摘要

蜡染工业是吉兰丹正在发展的纺织工业。生产单位废水处理不当，造成水污染。在蜡染工业废水中发现的最丰富和有害的污染物之一是罗丹明6G。采用纳米磁性复合吸附剂(NMAC)去除水溶液中的罗丹明6G。在本研究中，Box-Behnken设计被应用于获得染料去除的最佳条件模型。在最佳条件下，染料去除率最高达99.03%;初始染料浓度26.12 mg L−1，接触时间14.33 min，吸附剂剂量0.05 g，粒径190.26µm, pH为6.54。二次方程验证，预测结果与实验结果拟合率为99.97%。

Optimization of Rhodamine 6G removal from aqueous solution using Box-Behnken design

Batik industry is a growing textile industry in Kelantan. Improper treatment of wastewater from manufacture units leads to water pollution. One of the most abundant and harmful pollutants found in the batik industries effluents is Rhodamine 6G. A nanomagnetic adsorbent composite (NMAC) was used in this study to remove the Rhodamine 6G from aqueous solution. In this study, Box-Behnken Design is applied to obtain a model for optimum conditions for dye removal. A maximal dye removal (99.03%) was attained with optimum conditions; initial dye concentration of 26.12 mg L−1, contact time of 14.33 min, adsorbent dose of 0.05 g, particle size of 190.26 µm and pH of 6.54. A quadratic equation was validated with 99.97 % fit between predicted and experimental outcomes.
