INVESTIGATION OF NATURAL ADSORBENTS FOR DYE REMOVAL FROM TEXTILE WASTEWATER

Abstract

<p>The release of untreated textile wastewater introduces intense coloration into natural water bodies,<br>impacting aquatic ecosystems and water quality. This study examines the adsorption of methylene<br>blue (MB) dye using two natural adsorbents: moringa seed powder and lemon seed powder. Parameters<br>including contact time, adsorbent dose, pH, and initial dye concentration were optimized. Lemon seed<br>achieved 86% removal at pH 7 in 30 minutes, outperforming moringa seed’s 50% at pH 6 in 60<br>minutes. Adsorption data fit both Langmuir and Freundlich isotherms, indicating monolayer<br>adsorption and favorable conditions. These low-cost, locally available materials present an ecofriendly<br>alternative for dye removal.</p>
