摘要
水体中的苯甲酸污染已成为我国水污染中的一个主要问题,回收废水中的苯甲酸对保护环境具有十分重要的意义。本文以NKA-Ⅱ树脂作为吸附剂,研究NKA-Ⅱ树脂吸附水溶液中苯甲酸的影响因素,详细分析吸附剂质量、吸附温度和吸附时间对瞬时吸附量以及苯甲酸脱除率的影响,为大孔树脂处理含苯甲酸废水提供理论依据和参数指导。
Benzoic acid pollution in water was a major problem in China’ s water pollution, and the benzoic acid in recycled wastewater was of great signi？cance to protect the environment. Applied NKA-Ⅱ resin as adsorbent, the in？uence factors of benzoic acid absorption in aqueous solution were studied. The in？uence of adsorbent quality, adsorption temperature and adsorption time on instantaneous adsorption capacity and benzoic acid removal rate, were detailed investigated.
