Charcoal was produced from rambutan rods. The charcoal was then used as adsorbent to
adsorb copper ion 70 ppm dissolved in solution. The charcoal rambutan has ability to …

This Study aims to determine the adsorption process of Cu (II) metal by cassava peel waste
(Manihot esculenta crantz) meeting the Langmuir equation and Freundlich. Research …

This study proposes to determine the ability of activated charcoal from sugar palm bunches
(Arengga Pinnata MERR) as lead adsorbent (Pb), copper (Cu) and chromium (Cr). The …

The adsorption ability of rambutan charcoal with the size 100/200 mesh in absorbing
dissolved 70 ppm copper metal ions (Cu (II)) at pH 4.5 have evaluated. The adsorption …

Sugar palm fruit shells (SPFS) are abundant agricultural waste in Indonesia especially in
Aceh. It can be converted into activated carbon for heavy metal adsorption. This objective of …

Preparation and evaluation of activated carbon from the palm kernel shell (PKS), an
abundant agricultural residue, by physical and chemical activation were carried out. The …

Adsorbent is one of the most commonly used materials because of its high adsorption
effectiveness. However, adsorption with one type of adsorbent causes a lower adsorption …

The research on the effectiveness and characterization of quartz sand/coconut shell
charcoal composite as adsorbent of Manganese (Mn) heavy metal has carried out. Quartz …
