Custard Apple Leaves: A Green and Effective Adsorbent for Colourant in Wastewater Treatment
Year: 2024
Type: article
Abstract: The disposal of colorants in wastewater poses threats to aquatic organisms and can adversely affect the well-being of nearby residents.This study explores the effectiveness of using custard apple leaves to address water contamination caused by a colorant SADBS (Sodium 2-anilino-4-(2,4-dinitroanilino)benzene-1-sulfonate).Effect of the custard apple leaves on SADBS adsorption from water was studied by using parameters such as adsorbent amount, initial concentration and contact time, pH of solution.Under optimum conditions (the initial colorant concentration: 100 mg/L), about 91% of the colorants from the standard solution were eliminated.(pH value: 7.1, adsorbent quantity: 0.5 g, contact period: 60 min).The study's data were examined using Langmuir isotherm as well as Freundlich isotherm.The use of custard apple leaves as an adsorbent for SADBS is noteworthy.The desorption study also exhibited that about 93% of custard apple leaves were recovered by the process of applying acid-base treatment.
