Adsorption performance of activated carbon from tabebuia rosea for removal of methylene blue in aqueous solution / Nuri Afina Mohd Aris

This study emphasizes the agricultural waste from T. Rosea dried leaves as a natural low-cost adsorbent precursor of activated carbon for methylene blue dye solution due to its high abundance and availability in Malaysia. Methylene blue dyes which are largely consumed by textiles industry poses seve...
