The aim of this study was to examine the adsorption characteristics of cationic surfactant
modified-birnessite for removal of Pb. For this purpose, Na-birnessite and …

A low-cost and easily obtainable Nigerian bentonite (UAB) was utilized for the removal of
heavy metals (Nickel and Manganese) from a binary system. The bentonite was used …

In this paper, mesoporous birnessite-type manganese oxide (δ-MnO 2) was synthesized
using potassium permanganate and citric acid monohydrate through a simple redox method …

The kinetic, equilibrium modeling and adsorption characteristics of hydrous bismuth oxides
(HBOs) have been investigated for the removal of nitrate from aqueous solutions. The three …

Natural clays and materials such as bentonite, zeolite and sepiolite have been widely used
for environmental and agricultural purposes because of their easy application and relative …

The aim of this study is to remove Pb (II) and Cu (II) ions in binary and single solutions with
bentonite enriched with single bond SH groups (BSH) and to optimize the adsorption …

This work aims to study nitrate ions removal using Borassus aethiopum activated carbon (BA-
AC) in a synthetic medium. BA-AC was prepared through artisanal method in order to …

The adsorption behaviors of ammonium ions from aqueous solution by a novel
bioadsorbent, the Boston ivy (Parthenocissus tricuspidata) leaf powder (BPTL) were …

In this work, a low cost and abundant modified Iraqi bentonite was used for the removal of
heavy metal Cr+ 3 ions from wastewater by adsorption onto raw and activated bentonites …

Wastewater from rare earth mining (WREM) is very harmful to environment and human
health due to its high concentration of ammonia nitrogen (NH 3–N). It is therefore necessary …
