Enhancing photocatalytic degradation of beta-blocker drugs using TiO NPs/zeolite and ZnO NPs/zeolite as photocatalysts: optimization and kinetic investigations.

This study delves into the development and optimization of photocatalysts, namely ZnO NPs/Zeolite and TiO NPs/Zeolite, for the degradation of two beta-blocker drugs, including Atenolol (AT) and Metoprolol (ME). Structural and morphological analyses of the catalysts were conducted, and optimal conditions for drug degradation were determined using a Box-Behnken design. The results underscored the significant influence of pH, catalyst amount, drug concentration, and HO concentration on the degradation process using ZnO NPs/Zeolite and TiO NPs/Zeolite as the catalysts.

Efficient extraction of oleoresin from Ferula gummosa roots by natural deep eutectic solvent and its structure and chemical characterizations.

Deep eutectic solvents in the extraction of plant metabolites have found many advantages, such as low toxicity, biodegradability, low cost and ease of preparation over the conventional methods. This work aims to compare natural deep eutectic solvents in extraction and optimization of oleoresin from Ferula gummosa and determining its chemical and structure properties. Box-Behnken design was applied to optimize the extraction of oleoresin from Ferula gummosa using eutectic solvents.

Two-structured solid particle model for predicting and analyzing supercritical extraction performance.

Solid extraction process, using the supercritical fluid, is a modern science and technology, which has come in vogue regarding its considerable advantages. In the present article, a new and comprehensive model is presented for predicting the performance and separation yield of the supercritical extraction process. The base of process modeling is partial differential mass balances.
