Among the energy sources currently available that could address our insatiable appetite for
energy and minimize our CO2 emission, solar, wind, and nuclear energy currently occupy …

Over the past decades, the need for rare earth elements (REEs) has increased substantially,
mostly because these elements are used as valuable additives in advanced technologies …

Four hydrochars (labeled as HC, AHC, MHC, and MAHC, respectively) were prepared by
hydrothermal carbonization of bamboo with and without chlorane or followed by NaOH …

The adsorption performance of Cr (VI) on the Cr (VI)-imprinted poly (4-VP-co-MMA)(IIP)
supported on Activated Indonesia (Ende-Flores) natural zeolite (ANZ) structure for Cr (VI) …

Chemically modified bamboo (CMB) was utilized for removing methylene blue (MB) from
aqueous media in the present study. The adsorbent was characterized by Fourier transform …

The adsorption of methylene blue and indigo carmine, respectively a basic and an acid dye,
was studied on raw Brazil nut shells. The dye removal from solution by BNS was governed …

A method for the preconcentration of some transition elements at trace level was proposed
using a column filled with Amberlite XAD-2000 resin. Metal ions were adsorbed on XAD …

The present work proposes the use of Agave sisalana (sisal fiber) as an natural adsorbent
for ions Pb (II) and Cd (II) biosorption from natural waters. The flame atomic absorption …

A simple and accurate method was developed for separation and enrichment of trace levels
of gold in environmental samples. The method is based on the adsorption of Au (III) …

The present paper proposes an on-line pre-concentration procedure for lead determination
in drinking water and saline waste from oil refinery by flame atomic absorption spectrometry …
