Description

• Application: Adsorption of Thymol Blue dye from Aqueous solution using modified Chitosan.: This study explores the adsorption of Thymol Blue using chemically modified chitosan. Key parameters such as optimal time, pH, concentration, and dose were investigated, revealing that the adsorption process follows second-order kinetics (Elsawy et al., 2023). Electroorganic synthesis: bromination of thymol blue and phenol red.: This research details the electroorganic bromination of Thymol Blue, resulting in pH-sensitive products. The study provides experimental methods suitable for educational settings, emphasizing the ease of identifying brominated products (Ducci, 2023). Spectrophotometric Determination of Isopropamide Iodide based on Ion-pair Complex Formation with Thymol Blue.: This paper presents a spectrophotometric method for determining isopropamide iodide by forming an ion-pair complex with Thymol Blue, highlighting its application in analytical chemistry (Singh et al., 2020). A comparative photocatalytic degradation study of Thymol blue dye over pristine ZnO and Er-doped ZnO.: This study compares the photocatalytic degradation efficiency of Thymol Blue dye using ZnO and Er-doped ZnO, indicating the superior performance of the doped variant (Sharma et al., 2024).
