Arsenite Nanoparticle Adsorption 2D — pH-Dependent Water Remediation

Interactive 2D top-down model of iron-oxide nanoparticles scavenging dissolved arsenite (As(III)) from water: watch its acid-base speciation shift between neutral H3AsO3 and anionic H2AsO3- as pH changes, and see how that controls ligand-exchange adsorption capacity in real time.

This 2D top-down companion visualises how iron-oxide nanoparticles scavenge dissolved arsenite (As(III)) from contaminated water, and why that process is so sensitive to pH. Unlike arsenate, arsenite is mostly a neutral molecule (H₃AsO₃) below pH 9, so it can only be captured through direct ligand-exchange bonding to nanoparticle surface sites rather than simple electrostatic attraction. Drive the pH slider to see the real acid-base speciation shift between H₃AsO₃ and H₂AsO₃⁻, watch a Gaussian capture-probability curve centred on the iron oxide's point of zero charge, and track adsorption build up live as particles undergo Brownian motion toward nanoparticle surfaces in a pannable, zoomable reactor view — with nanoparticle dose and competing-anion load as the other two real levers used in actual groundwater treatment design.

⚙ Under the hood

A 2D top-down companion to the 3D reactor model: iron-oxide nanoparticles scavenge dissolved arsenite (As(III)) from water as its acid-base speciation shifts between neutral H3AsO3 and anionic H2AsO3- with pH, and a Gaussian ligand-exchange capture probability centred on the nanoparticle's point of zero charge controls adsorption in real time, in a pannable, zoomable reactor view.
