Abstract
Phosphogypsum (PG) is an acidic by-product that is created during the production of phosphoric acid using the sulfuric acid route. The management of PG poses a significant environmental challenge worldwide due to its large quantity and chemical composition. While PG primarily consists of calcium sulfate dihydrate, it also contains various impurities such as phosphorus, fluoride, heavy metals, and radionuclides. These toxic impurities, when present in high concentrations, can have adverse effects on the environment and human health. In this review, we provide a detailed examination of the behavior of the most abundant impurities found in PG. Furthermore, we discuss the factors that influence the presence of different types of impurities in PG. Understanding the overall behavior of these impurities is crucial for selecting appropriate environmental methods for PG management and identifying suitable avenues for its valorization.
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.
