Flow injection potentiometric stripping analysis for study of adsorption of heavy metal ions onto modified diatomite

Mercury(II) removal from water by electrocoagulation using aluminium and iron electrodes

“…The current peak was used to calculate the removal percentage of mercury(II) ions. During these investigations, 5 mL of electrolytic solution and 5 mL of the filtrate were mixed in a 50 mL volumetric flask, and then extended the whole to the gauge mark with deionised water [19][20][21]. The content was poured in a conventional cell of three electrodes (Au-SCE-Pt) and analyzed.…”

Adsorption of Cd (II) and Zn (II) from aqueous solutions using magnetic hydroxyapatite nanoparticles as adsorbents

“…It is reported that zeolite [6,7], montmorillonite [8,9], rectorite [10,11], diatomite [12,13] and other mineral materials can treat wastewater by adsorption, ion exchange, precipitation and surface complexation because of their excellent surface characteristics and ion adsorption and exchange performance. As the mineral materials have the advantages of wide sources, low cost, simple process, easy use and no regeneration, mineral materials of novel environmental functions will have a great scientific, social and economic significance.…”

The separation of uranium ions by natural and modified diatomite from aqueous solution

“…The silanol group is an active component tending to react with many polar organic compounds and various functional groups. Different methods of the diatomite modification allowing to increase its adsorption properties are described [21][22][23]. In particular, an organophilic surface and interlayer environment can be produced by replacing naturally occurring inorganic cations with various organic cations [24].…”
