In this study, the toxic cationic dye of methylene blue (MB) was encapsulated by the polymeric natural carbohydrate of turmeric powder (TP) adsorbent. The natural TP adsorbent was characterized to define the functional groups existing for complexation ability to the MB dye molecules. The MB dye adso...

The ligand based composite material is an effective material for the removal of diverse contaminants from wastewater. However, the performance of some ligands functionality is limited in many cases due to the functional complexation ability. Therefore, the high immobilization of ligand anchoring by ...

Three adsorbents, namely, bentonite–alginate beads, activated carbon–alginate beads, and activated carbon–bentonite–alginate beads (ABA) were prepared for the adsorption of methylene blue (MB). The effects of solution pH (3–11), temperature (30, 40, and 50 °C), initial concentration (25–500 mg/L), a...

Mesoporous activated carbon was prepared using a hydrochar derived from coconut shell waste through hydrothermal carbonization and NaOH chemical activation process (COSHTC). Three sets of activated carbons were obtained with different hydrochar:NaOH impregnation ratios (1:1, 1:2, and 1:3). Among the...
