Procion Red HE-7B was directly immobilized onto STREAMLINE matrix to obtain a moderately substituted dye-ligand matrix in which the dye concentration was 6.72μmol/ml adsorbent. The adsorption characteristics of alcohol dehydrogenase (ADH) onto the sticky dyed adsorbent in the absence and/or presence of yeast cells and cell debris were investigated. The Langmuir-type isotherm model was reasonably used...
Strontium (Sr) ions in aqueous solutions could be adsorbed by root tissue powders of Amaranthus spinosus, a common weed found in the fields. The adsorption isotherm could be fitted by either the Langmuir or the Freundlich model with the maximum adsorption capacity being 12.89 mg/g from the Langmuir isotherm. The maximum adsorption capacity of the biosorbent decreased with increasing temperature,...
