Removal of Methyl Orange from Aqueous Solution Using Orange Peel as a Low-Cost Adsorbent.

The research article discusses the use of orange peel as a low-cost adsorbent for removing methyl orange dye from water solutions. The study found that increasing contact time, adsorbent dose, and decreasing particle size led to higher removal of the dye. However, increasing the initial concentration of the dye decreased the removal percentage. The Langmuir isotherm model was found to best fit the experimental data. Overall, orange peel was found to be an effective and affordable adsorbent for water treatment. Another article by Li et al. explores the use of sludge-based activated carbon for removing dyes from water, highlighting its potential as a sustainable and cost-effective solution.
