Chemical precipitation using lime (Ca (OH) 2), caustic soda (NaOH) and soda ash (Na 2 CO
3) for the removal of simultaneous heavy metals (Cu (II) and Zn (II)) from industrial …

In the present research, a biopolymer Chitosan (C) grafted with ethylenediamine (EDA) and
methyl acrylate (MA) were compared for the adsorption of Congo red dye from aqueous …

Five adsorbents based on fly ash treated with NaOH for the adsorption of cadmium ion from
aqueous solutions were investigated. The materials were characterized using scanning …

The initial characteristics of Romanian fly ash from the CET II Holboca power plant show the
feasibility of its application for the production of a new material with applicability in …

Anthropogenic activity in Antarctica has increased due to the various scientific expeditions
and tourism. Lake water sampling was carried out during the 34th Indian Scientific …

Biochar-supported nanoscale zero-valent iron (800nZVI/BC) was prepared by carbothermal
synthesis to remedy Cr (VI) wastewater. More than 99% of Cr (VI) was efficiently removed …

The study focuses on synthesizing cinnamon-bentonite-loaded chitosan nanospikes for the
enhanced removal of Congo red, a hazardous dye commonly found in textile wastewater …

Immobilization of toxic compounds on the solids limits their bioavailability in natural
ecosystems. The use of waste-derived adsorbents for this purpose has additional benefit …

In this study, chitosan was chemically modified with only diammonium phosphate (DAP) and
DAP/EDTA (ethylenediaminetetraacetic acid) mixture for the removal of Pb (II) ions from …

A combined amendment (CF) consisting of 90% calcium sulfate (CaSO 4) and 10% ferric
oxide (Fe 2 O 3) was used to investigate the feasibility, active principles, and possible …
