Introduction

Jingqi Zhang is an inventor based in Beijing, China, associated with Beijing University of Chemical Technology. Her patent work addresses the removal of pollutants from contaminated water using a composite material designed to form layered double hydroxide precipitates in situ.

Latest Patents

The provided information lists one patent for Zhang: “Composite Material and Method for Removing Pollutant from Polluted Water.” The invention uses an aluminum-based composite containing one or more alkaline-earth or transition metals. As the material dissolves, it releases metal and hydroxide ions that interact with ions in contaminated water, forming layered double hydroxide precipitates that can capture pollutants.

The composite is specified as containing 18–70 weight percent aluminum, 30–80 weight percent of a second metal, and up to 2 weight percent auxiliary agent, with particle sizes ranging from 0.01 to 3 millimeters. Pretreatment with dilute hydrochloric acid can help form a micro-nano Alloy@LDH composite with a core-shell structure. The invention is described for soil remediation and sewage purification, including the removal or degradation of complex contaminants across acidic to alkaline conditions.

Career Highlights

Zhang’s listed patent reflects work on materials-based approaches to environmental remediation. The invention combines alloy composition and in situ precipitation to address pollutant removal in water and soil.
