Removal of malachite green from aqueous solution using low-cost chlorella-based biomass

Tsai, Wen-Tien, Chen, Huei-Ru·2010·Journal of Hazardous Materials

Abstract

Chlorella-based biomass from the algae-manufacturing waste was used as a low-cost biosorbent for the biosorption of malachite green (MG) in an agitated batch experiments with respect to its kinetics as a function of agitation speed (i.e., 300-500 rpm), initial MG concentration (i.e., 2.0-20.0 mg dm(-3)), biosorbent loading (i.e., 0.5-2.0 g/2.0 dm(3)), initial pH (i.e., 3.0-11.0), and temperature (i.e., 278-318 K). The experimental data revealed that the rapid removal of cationic solute using the dead microalgae significantly depended on the initial MG concentration and algal loading. Furthermore, the biosorption kinetics well obeyed the pseudo-second-order rate equation, and could be elucidated by considering the electrostatic interactions. According to the biosorption behaviors of MG from aqueous solution using chlorella-based biomass in comparison with commercial activated carbon, this work also showed that the biosorbent can be effectively used as a low-cost biosorbent for the removal of MG from its aqueous solutions.

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.
