A new artemisinin sustained-release particle (ASP) was developed that significantly inhibits Microcystis aeruginosa (M. aeruginosa) growth. The physical and chemical properties of ASPs were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), differential scanning calorimetry, and thermogravimetry (DSC-TG). The results demonstrated that ASPs are thermally stable and have sustained-release properties. On the sixth day, the ASPs (0.2 g L) inhibited M. aeruginosa with an inhibition rate (IR) greater than 70%. Additionally, ASPs inhibited M. aeruginosa without increasing microcystin-LR release (MC-LR). This research offers a novel approach to the management of cyanobacterial blooms.
一种新型青蒿素缓释颗粒（ASP）被研发出来，它能显著抑制铜绿微囊藻（M. aeruginosa）的生长。利用扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、差示扫描量热法和热重分析法（DSC-TG）对ASP的物理和化学性质进行了表征。结果表明，ASP具有热稳定性和缓释特性。在第六天，浓度为0.2 g/L的ASP对铜绿微囊藻的抑制率大于70%。此外，ASP在抑制铜绿微囊藻的同时不会增加微囊藻毒素-LR（MC-LR）的释放。该研究为蓝藻水华治理提供了一种新方法。
