| 摘 要： | 采用累托石作为水中碱性桃红的吸附剂.考察了振荡时间、pH值、累托石用量、碱性桃红初始浓度等因素对吸附效果的影响.测定了吸附等温线,对吸附动力学规律进行了数学模拟.结果表明,振荡时间、累托石用量、碱性桃红初始浓度等因素对吸附效果有重要影响.对于初始质量浓度为50 mg/L的碱性桃红水溶液,最适宜吸附条件为:振荡时间30 min,累托石用量200 mg/100 mL,pH值为6.累托石对水中碱性桃红的吸附等温线呈"S"型,等温吸附规律可用Freundlich模式较好地描述,吸附动力学规律可用Bangham公式模拟.

| Abstract: | Rectorite is used as adsorbent to dispose basic safranine in water in this paper.Effects of shaking time,pH value,rectorite dosage and initial concentration of basic safranine on the adsorption efficiencies are inspected.Adsorption isotherm is determined,and adsorption kinetics law is simulated by Bangham formula.The results show that shaking time,pH value,rectorite dosage and initial concentration of basic safranine are the main factors to affect adsorption efficiencies.To basic safranine solutions with in... |
