Adsorption of heavy metals by green algae and ground rice hulls
Abstract
This research demonstrates the applicability of low cost, readily available alternate adsorbents to remove and recover toxic heavy metals from water. Heavy metal ion adsorption has been investigated using two different adsorbing biomasses, algae and rice hulls. Algal biomass adsorption studies were conducted with: As, Cd, Co, Cr, Pb, Ni and Zn, and rice hull biomass adsorption studies were conducted with: As, Cd, Cr, Pb and Sr. Both biomasses were dried and pulverized to maximize surface area. The green alga, Chlorella minutissima, adsorbed greater than 90% of the initial Pb, and greater than 98% of the initial Co concentrations. Rice hulls (Mars and Rico Varieties) exhibited similar adsorption percentages: 94% for Sr, and greater than 99% for Pb. The rate of adsorption was fast; the solution metal concentration reached equilibrium within minutes. The cell wall metal complex was found to be stable; the bound metal did not desorb over time under static conditions. Most cationic metal ions could be recovered from the biomass through desorption by lowering the pH of the medium.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
