Introduction

Hongwen Sun is a notable inventor based in Tianjin, China. He has made significant contributions to the field of environmental science, particularly in the detection of microplastics. His innovative methods aim to address pressing environmental issues related to pollution.

Latest Patents

Hongwen Sun holds a patent for a method titled "Method for quantitative detection of trace polylactic acid microplastics in environmental sample." This method involves the depolymerization of polylactic acid microplastics in an alkaline alcohol phase system. The resulting lactic acid molecules are separated and recovered. The mass concentrations of lactic acid before and after the reaction are quantitatively detected using HPLC-MS. This allows for the calculation of the initial mass concentration of PLA MPs in the sample. The method can detect concentrations as low as 0.05 mg/kg, making it highly effective for quantifying trace PLA in various environmental samples, including water, sludge, sediment, dust, and soil.
