Research ArticleOpen accessBiosorption of Cr(III) by Microalgae and Macroalgae: Equilibrium of the ProcessIzabela Michalak, Agnieszka Zielinska, Katarzyna Chojnacka, Jan MatulaEquilibrium experiments of chromium(III) biosorption by microalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best operation conditions for the process were selected: pH … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,204 accessesView PDF Cite
