摘要 采用蟹壳为原料制备改性的环境友好型改性甲壳素吸附剂,考察了吸附剂对抑菌消毒剂苯扎氯铵(BACs)的吸附影响因素,并制备了改性甲壳素包裹苯扎氯铵凝胶,考察凝胶对金黄色葡萄球菌、大肠杆菌、腐败菌的抑菌效果。研究结果表明,制备的改性甲壳素吸附剂表面存在大量松散的孔隙结构,具有很强的吸附能力。改性甲壳素吸附剂可以作为来源、酸碱性不同的BACs吸附剂,对BACs浓度范围在2.5 mg/L~80 mg/L的溶液中的BACs都具有非常快速而高效的吸附作用。吸附BACs所制备的ICH-BAC水凝胶对金黄色葡萄球菌、大肠杆菌、腐败菌等都具有非常好的离体抑菌活性。 A modified environmentally benign modified chitin adsorbent was prepared to use crab shells as raw material,and the factors affecting the adsorption of the adsorbent on the bacteriostatic disinfectant benzalkonium chloride were investigated.And a modified chitin-encapsulated benzalkonium chloride gel was prepared.The bacteriostatic effect of the gel on Staphylococcus aureus,Escherichia coli and spoilage bacteria was examined.The results illustrated that a grand number of loose pore structures existed on the surface of the prepared modified chitin adsorbent,which had a strong adsorption capacity.The modified chitin adsorbent can be used as an adsorbent for BACs of various sources,acidity and alkalinity,and has an exceedingly fast and efficient adsorption of BACs in solutions with BACs concentrations ranging from 2.5 mg/L~80 mg/L.The ICH-BAC hydrogel prepared by adsorption of BACs showed exceedingly good in vitro bacteriostatic activity against Staphylococcus aureus,Escherichia coli and spoilage bacteria.
