Synthesis and characterization of adsorbent derived from pandan leaves for methylene blue removal

Dyes are an important type of pollutants that come in a large amounts which originated from industries such as textile, paper and pulp making, and petroleum. The elimination of dyes from wastewater is challenging as they have a synthetic origin and possess complex aromatic molecular structures which...
