Hydronium ions pass through the proton exchange membrane, which is a solid electrolyte in electrochemical cell.

Formation of the organic-inorganic proton exchange membrane

The low Cd biosorption at pH less than 4 has been suggested to the competition among metal ions from hydronium ions for the available biosorption sites.

Biosorption of [Cd.sup.2+] from aqueous solutions by tolerant fungus Humicola sp

No adsorption was observed at low pH values due to opposition of hydronium ions with the metal ions.

Synthesis of Novel Schiff Based Xerogel Silica for Adsorption of Cr(III) and Pb(II)Ions

One of the main effects of the medium's pH over the sorption process is related to presence of hydronium ions which may cause the protonation of the adsorption sites (obviously this process is more evident at low pHs).

Cassava root husks as a sorbent material for the uptake and pre-concentration of cadmium(II) from aqueous media

At low pH, the surface of the adsorbent was surrounded by hydronium ions that compete with metal ions, which prevented the metal ions approaching the binding sites on the adsorbent.

Betel-nut Peel as an Adsorbent in the Removal of Cd, Cr and Pb from Aqueous Solutions

These nitrogen radicals then interact with moisture in the atmosphere to create hydronium ions.

Advanced development continues to minimize sample prep: while sample preparation work continues as the largest lab bottleneck, recent innovations are working to reduce that workload and increase performance
