Adsorption of rhodamine B by palm kernel shell adsorbents
This study was aimed at evaluating the adsorptive removal of rhodamine B dye (RhB) by palm kernel shell adsorbents. The precursor was mixed with potassium hydroxide solution, and the mixture was further heated using furnace (FC) and microwave (MC). Microwave-assisted water (steam) treatment (MH) of...
