Remoção de fármacos via adsorção utilizando hidróxidos duplos lamelares: uma análise bibliométrica

Abstract

Drugs are compounds that have risks associated with their presence in the environment, as they can lead to the emergence of resistant bacteria. It is also possible to highlight the removal of these substances through conventional treatment processes, which leads to the need for other removal techniques, such as adsorption. Double lamellar hydroxides have attracted attention due to their applications as an adsorbent in the removal of drugs from aqueous matrices, due to their properties, easy synthesis and low production cost. This bibliometric analysis aims to evaluate the potential interest in the adsorption of pharmaceutical compounds using HDLs through bibliometric analysis and to study the main parameters and mechanisms that govern this phenomenon. 206,129 documents were retrieved, 1767 of which focused on the use of these materials in the remediation of effluents. The number of works chosen to use the adsorptive property of HDLs was 1,297. Among the countries with the highest number of publications in this area, Brazil is in fourth place, which demonstrates the wide applicability of double layer hydroxides in the treatment of effluents, especially pharmaceuticals.
