摘　　要：以7种常见的塑料颗粒为研究对象,探究60℃的恒温条件下消解液浓度、消解时间对塑料颗粒表面特征及质量的影响。结果表明,以5%NaOH作为消解液,60℃处理24 h,微塑料的表面特征及质量变化最小。Seven common microplastic particles as the reach object,the surface characteristics and quality of plastic particles were investigated at a constant temperature of 60℃with different concentration of digestion solution and different digestion time under the condition of static.The results show that:5%NaOH as digestion solution under static condition and digested for 24 h,it has the least influence on the surface characteristics and quality of microplastics.
