The presence of Pb (II) ions, as a major pollutant source, in the water resources causes
global health concerns. The adsorption method has been conventionally used for the …

The adsorption mechanism of the removal of lead from water by using carboxylic functional
group (COOH) functionalized on the surface of carbon nanotubes was investigated. Four …

The environmental application of carbon nanotubes supported by activated carbon to
remove chromium (VI) ions from polluted water was investigated. The experimental …

The powdered activated carbon (AC) supported by carbonaceous nano-adsorbents were
examined to remove hexavalent chromium [Cr (VI)] from aqueous solution The adsorption …

This study was carried out to evaluate the environmental application of modified and
nonmodified carbon nanotubes through the experiment removal of chromium trivalent (III) …

Chitosan (CHT) and poly (vinyl alcohol)(PVA) films, with different mass ratios between
CHT/PVA, were prepared to be applied as devices for removal of Pb (II). The …

In this study, Pb2+ removal from wastewater using multiwall carbon nanotubes (MWCNTs)
was investigated. XRD, SEM-EDX, BET, and FTIR were employed for MWCNT …

Four types of carbonaceous adsorbent materials were applied for the removal of cadmium
ions from water. These materials include fly ash (FA), activated carbon (AC), carbon …

The spill of crude oil on the soil contaminates it, causing cancer, a dearth of vegetation,
livestock deaths, and forced migrations. The petroleum hydrocarbon (TPH) was removed …

The raw carbon nanotubes (CNTs) were prepared by the floating catalyst chemical vapor
deposition method. The raw carbon nanotubes were functionalized, impregnated with iron …
