The use of adsorbent pellets of natural bentonite, kaolin and zeolite is analyzed in this work to study the removal capacity of heavy metals from wastewaters. Adsorbent pelets made with different alum
Spent tea-supported magnetite (ST/Mag) nanoparticles were synthesized as an adsorbent for the removal of hexavalent chromium [Cr(VI)] from saline wastewater. Prepared ST/Mag adsorbent was characterize
The adsorption process is an alternative for treating natural and waste waters, with heavy metals. Oxidic lithological materials, rich in iron and aluminum amphoteric oxides, with pH-dependent surface
