The use of Cu in daily life and industry can produce toxic waste, both for the human body
and the environment. This study aimed to determine the optimum pH value and contact time …

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 …

In this study, sugarcane bagasse (SCB) as a cheap and effective biosorbent was used for
copper ions (Cu (II)) removal and modification was performed on SCB with HCl chemical …

This study aims to determine: the ability of corn cobs and eggshells as Zn metal adsorbents,
functional groups of corn cobs and eggshells adsorbent, what isotherm patterns occur in the …

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 …

Abstract Copper metal (Cu2+) pollution gives bad impact for society life. One effort to reduce
the content of copper metal by using adsorption process. This research used physical …

Adsorption of heavy metal ion Cu (II) onto modified lignin from sawdust waste have been
presented. The ability of lignin from sawdust waste to adsorb the copper ion has been …

In this study, the purpose of our interest is to investigatethe adsorption behavior of copper (II)
ions in aqueous solution using some tannin-rich plants as natural bio-adsorbents such as …

The objective of this study was to characterize the parameter conditions such as optimum
weight, contact time, pH, and concentration of the copper solution upon the absorption of …

The adsorption process using cornstalk as adsorbent was used to remove the single metal
ion such as copper ion and cadmium ion. The adsorption kinetics of each contaminant then …
