Abstract
The large-scale accumulation of industrial by-product gypsum has led to land embezzlement and serious environmental pollution. Meanwhile, as a predominantly used nitrogen fertilizer, urea shows a disadvantage of high solubility in soil. Therefore, it can hydrolyze into large amounts of ammonium salts so rapidly that cannot be absorbed efficiently by crops. The sustainable method of using industrial by-product gypsum to synthesize urea gypsum cocrystals is a promising way to solve above challenges. The synthesized urea gypsum shows low aqueous solubility and hygroscopicity, which can be used as sustained release fertilizer. In this review, the present status regarding urea gypsum is systematically reviewed, including its development history, preparation methods, impact of different raw materials, evaluation of products performance, and large-scale trials. This review aims to reveal the current situation, identify current gaps, and provide suggestions for future investigations concerning urea gypsum.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
