Copper and cobalt can be found on nickel laterite ores, and cobalt can be found also on
copper ores, and many contaminants such as iron, aluminum, and magnesium are …

Many global mining activities release large amounts of acidic mine drainage with high levels
of manganese (Mn) having potentially detrimental effects on the environment. This review …

The adsorption of metals using unmodified cellulose is often unsatisfactory owing to
insufficient active functional groups on its surface. The objective of this work is to modify …

Heavy metal ion pollution in water and soil is a formidable environmental problem. Due to
their desired heavy metal capture capacity and excellent chemical and physical stability …

Water purification from toxic metals was the main objective of this work. A composite in film
form was prepared from the biomaterials hydroxyapatite, chitosan and glycerol using the …

The aim of this study is to develop a new, efficient, and inexpensive natural-based adsorbent
with high efficacy for the cationic dye methylene blue (MB). A natural-based nanocomposite …

The pollution of heavy metal ions in water poses a serious threat to human being and
ecosystems. Here, we report polyamidoxime (PAO) brush grafted graphene oxide (GO) as a …

Hydroxyapatite (HAp) synthesized through a wet chemical procedure was used to adsorb
lead (II) from an aqueous solution. HAp was characterized using Fourier transform infrared …

Adsorption of Hg (II) ions onto selective adsorbent of dithizone-immobilized natural zeolite
(DIZ) from Wonosari, Yogyakarta, Indonesia has been investigated in batch mode. Some …

Red mud, a by-product produced in the alumina industry, has been considered as a serious
environmental burden. In this study red mud and three modified samples were used as …
