The demand for valuable metals such as rare earth elements and platinum group metals is
rising fast in the context of the depletion of natural resources and international conflicts …

Adsorption is a promising clean water technology process. Many materials both inorganic
(such as zeolite, clays) and organic (such as residues from agricultural industry) have been …

This review examines the performance of new highly promising materials in water
purification industry. Low-cost and effective industrial wastes may have ample applications …

Locally available apricot (Prunus armeniaca L.) shells classified as a waste product from fruit
processing, were alkali activated in order to develop an efficient heavy metal ions sorbent for …

The development of distinct biochar from agricultural waste for soil and environment
remediation is valuable. Moderate pretreatment with sodium hydroxide may open the …

In this study, the adsorption behavior of copper (II) ions from aqueous solutions onto sesame
husk (SH) was investigated. The effect of different parameters such as pH, contact time …

This research aims to remove two phenothiazines, promazine (PRO) and promethazine
(PMT), from their individual and binary mixtures using olive tree pruning biochar (BC-OTPR) …

In the present paper, the lignocellulosic residues from the olive oil industry in South-East
Italy, namely BOP (Biosorbent from Oil Production), were used as sorbents for heavy metals …

A modified polymer (chitosan grafted with sulfonic acid and cross-linked with
glutaraldehyde) was synthesized in order to examine the effect of humic acid (HA) on the …

In this work, chrome-tanned leather waste were activated with sodium hydroxide (NaOH) to
prepare a porous adsorbent for lead (II) adsorption. The effects of various preparation …
