    • 摘要: To improve the adsorption performance of citrus pulp(CP),using cationic(3-chloro-2-hydroxypropyl)trimethylammonium chloride(CHPTAC),as monomer,CHPTAC-modified citrus pulps(CP-CHPTAC)were prepared under alkaline condition.The adsorption behavior to the anionic dye Congo red was investigated.The effects of the amount of CHPTAC,initial concentration of Congo red,adsorption time and pH value on the adsorption were tested.The isothermal adsorption model and adsorption kinetics were also analyzed.The results showed that with the increase of CHPTAC dosage,the equilibrium adsorption capacity of Congo red increased.At a pH of 4.6 and adsorption temperature of 25 °C,the decolorization rate of Congo red reached 94%by CP-CHPTAC with graft ratio of 20.6%,and the adsorption process conform to the Langmuir isotherm model and pseudo-second-order kinetic model.The CP-CHPTAC suggested a good reusability and stability as it exhibited remarkable adsorption efficiency on Congo red after 6 times regeneration cycles.%为提高柑橘渣(CP)的吸附性能,以(3-氯-2-羟丙基)三甲基氯化铵(CHPTAC)为阳离子单体,在碱性条件下对柑橘渣进行改性,制备了阳离子改性柑橘渣(CP-CHPTAC).研究了该吸附剂对阴离子染料刚果红的吸附行为,考察了CHPTAC用量、刚果红溶液初始浓度、吸附时间和pH值对吸附效果的影响,并对等温吸附模型和吸附动力学进行分析.结果表明,随着CHPTAC接枝率的增大,刚果红平衡吸附量提高; 在pH值4.6,吸附温度25°C条件下,接枝率为20.6%的CP-CHPTAC对刚果红的脱色率达94%以上,吸附过程符合Langmuir等温吸附模型及伪二级动力学模型.CP-CHPTAC经过6次再生测试后,对刚果红仍有良好的吸附效果,显示出优异的重复使用性和稳定性.

    • 摘要: Raw material Banana peel (BP), was decolorized, and then was modified with 3-Chloro-2-hydroxypropyltrimethylammonium chloride to prepare modified banana peel bioabsorbent (MBP). The adsorbents were characterized by scanning electron microscopy. After modification, the adsorption capacity of MBP was higher than that of BP under the same conditions. The effects of solution pH, amount of adsorbent, metal ion concentration and adsorption time on the adsorption properties of Cr (Ⅵ) from aqueous solution were investigated. The results showed that the optimum solution pH was 2.0 and the optimum adsorbent was 4-5 g/L. The adsorption amount of MBP on Cr (Ⅵ) increases with the increase of metal ion concentration in solution. The adsorption isotherm was in accordance with the Langmuir monolayer adsorption model. The maximum adsorption capacity of MBP to Cr (Ⅵ) was 58.82 mg/g at 40°C. The adsorption of Cr (Ⅵ) by MBP reached the adsorption equilibrium at 150 min, and the adsorption kinetics was consistent with the quasi –second-order kinetic equation.%以香蕉皮(BP)为原料,脱色后通过3-氯-2-羟丙基三甲基氯化铵改性制备新型香蕉皮生物吸附剂MBP.采用扫描电镜对吸附剂进行表征.经改性后,同等条件下MBP比BP的吸附量提高.考察溶液pH、吸附剂用量、金属离子浓度和吸附时间对其从水溶液中吸附Cr(Ⅵ)的吸附性能的影响.结果表明,最佳的溶液pH值为2.0,最佳吸附剂用量4-5 g/L.MBP对Cr(Ⅵ)的吸附量随溶液中金属离子浓度的增加而增加,吸附等温线符合Langmuir单分子层吸附模型,MBP在40°C对Cr(Ⅵ)的最大吸附量为58.82 mg/g;MBP对Cr(Ⅵ)的吸附,在150 min时基本上达到吸附平衡,吸附动力学符合准二级动力学方程.

Orthogonal experiment and the single factor experiments were adopted to optimize the reaction conditions. The structures of MSF were characterized by FT-IR,ESEM and TGA. The optimization conditions were summarized as follows:the amount of 40%NaOH was 5mL,the mass ratio of starch to etherification agent value was 1,the reaction temperature was 55°C,and the reaction time was 5 hours. Under the above optimal conditions,the obtained flocculant showed high CODCr removal,i. e. ,84.6%for the ink wastewater. The characterization results showed that the MSF’s structure was neat,arrange compact and had good thermal stability. By ESEM,it could be seen that strach had obvious changes,conforming to the etherification of strach modification.
