REMOVAL OF CRYSTAL VIOLET DYE FROM WASTEWATER USING SYNTHESIZED ACTIVATED CARBON FROM ADANSONIA DIGITATA IN TWO DIFFERENT GEOGRAPHICAL REGIONS OF SATARA DISTRICT

Abstract

The increasing presence of synthetic dyes, such as crystal violet dye (CVD), in wastewater poses significant environmental, aquatic and health challenges. This study focuses on the synthesis of two types of activated carbon from Adansonia digitata (baobab) tree branch which was collected from Dahiwadi, and Menavali in Satara district, a cost-effective and sustainable adsorbent for dye removal. Activated carbon(AC) was produced by chemical activation with potassium hydroxide (KOH) followed by thermal treatment. This Activated Carbon was characterized using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analysis. Batch adsorption experiments were carried out to assess the impact on essential parameters, including initial dye concentration, pH, adsorbent dosage and contact time. The results demonstrated high adsorption efficiency, with a maximum removal percentage exceeding 99.09% under optimal conditions. This study highlights the potential of Adansonia digitata tree branch (ADTB) waste-derived activated carbon as an eco-friendly and efficient solution for treating dye-contaminated water.
