采用殼聚糖為原料，戊二醛進(jìn)行交聯(lián),氯乙酸進(jìn)行羧甲基化，制得羧甲基殼聚糖微球；然后以Ni2+為印跡離子通過分子印跡技術(shù)改性羧甲基殼聚糖微球，制得印跡改性羧甲基殼聚糖微球�？疾炝随嚌舛�、戊二醛用量、洗脫時(shí)間等因素對(duì)印跡交聯(lián)改性的影響，實(shí)驗(yàn)結(jié)果顯示最佳印跡改性條件為：鎳離子濃度5g/L、戊二醛用量20mL、洗脫時(shí)間7h。探討了印跡改性羧甲基殼聚糖微球吸附鎳的影響因素，選出最佳吸附條件，結(jié)果表明：pH=8、60mg吸附劑用量、80min吸附時(shí)間、25℃吸附溫度為最佳吸附條件。對(duì)自制的印跡改性羧甲基殼聚糖微球與殼聚糖用含Ni2+廢水進(jìn)行了吸附效果對(duì)比，其吸附率分別為62.45%和47.97%，表明印跡改性羧甲基殼聚糖微球的吸附性能相對(duì)與殼聚糖有了較大的提升。 如果寫的太差，請(qǐng)幫忙翻譯一下。。Carboxymethyl chitosan microspheres were prepared as raw product using chitosan as original material, glutaraldehyde as the cross-linking agent,and chloroacetic acid as the carboxymethylation substance.Then modified by molecular imprinting technology using Ni2+ ion as template.for use in the adsorbtion of Ni2+.The condition of imprinting modification and absotbtion were studied.The results showed that the best modification was got when Ni2+ concentration was 5g/L,glutaraldehyde dosage was 20mL and elutingtime is 7h and the maximum adsorbtion for Ni2+ occured at pH=8, adsorbentdosage was 60 mg,adsorption time was 80 min and adsorption temperature was 25℃.Compared absorbtions of modified carboxymethyl chitosan microspheres and chitosan to Ni2+ in wastewater which were 62.45% and 47.97%,indicating that the absorbtion property of the former is better. |

| Carboxymethyl chitosan microspheres were prepared by using chitosan as the original material, glutaraldehyde as the cross-linking agent, and chloroacetic acid as the carboxymethylation substance. Then the microspheres were furtherly modified by molecular imprinting technology using Ni2+ ion as template, to obtain the imprinted modified carboxymethyl chitosan microspheres. The influence of nickel concentration, the glutaraldehyde dosage, and elution time on the imprinted cross-linked modification was investigated. The results showed that the best modified conditions were: 5g/L Ni2+ concentration, 20mL glutaraldehyde and 7h elution time. The best adsorption conditions，where the maximum adsorption of nickel by modified carboxymethyl chitosan microspheres occurred，were that：pH=8, adsorbent dosage was 60 mg, adsorption time was 80 min and adsorption temperature was 25℃. We also compared the adsorption effects between self - made imprinting modified carboxymethyl chitosan microspheres and chitosan by using Ni2+-containing wastewater, and the adsorption rates were 62.45% and 47.97% respectively, indicating that the adsorption properties of modified carboxymethyl chitosan microspheres have been greatly improved. |
