利用FT-IR、UV、TG-DTA和XRD手段,对合成的硫脲壳聚糖及硫脲壳聚糖-Zn(Ⅱ)配合物进行了表征,研究了壳聚糖、硫脲壳聚糖及硫脲壳聚糖-Zn(Ⅱ)配合物对细菌大肠杆菌、金黄色葡萄球菌和真菌黑曲霉的抑菌性能。结果表明:合成的硫脲壳聚糖-Zn(Ⅱ)配合物对大肠杆菌、金黄色葡萄球菌的抑菌性能比单一的壳聚糖、硫脲壳聚糖显著提高,对真菌黑曲霉亦具有较强的抑制作用。
The synthesized thiourea chitosan and thiourea chitosan-Zn (Ⅱ) complexes were characterized by FT-IR, UV, TG-DTA and XRD. The effects of chitosan, thiourea chitosan And thiourea chitosan-Zn (Ⅱ) complex on bacteria Escherichia coli, Staphylococcus aureus and fungal Aspergillus niger antibacterial activity. The results showed that the antibacterial activity of the synthesized thiourea chitosan-Zn (Ⅱ) complex against Escherichia coli and Staphylococcus aureus was significantly higher than that of the single chitosan and thiourea chitosan, Strong inhibitory effect.
