متن کاملSawdust as a natural and low cost adsorbent for the removal of brilliant cresyl blue dye from water samples
Sawdust which is the main waste from wood industry has been used as a raw material forremoval of Brilliant Cresyl Blue toxic dye. The effects of various parameters such as pH,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg L-1. The optimum condition for the studiedparameters was applied for various con...

متن کاملStudies on optimization of efficient parameters for removal of lead from aqueous solutions by natural zeolite as a low-cost adsorbent using response surface methodology
In this research, the removal of lead from the aqueous solution was investigated using natural nontoxic zeolite (clinoptilolite) as a low-cost adsorbent in order to reduce human exposure to it. The clinoptilolite zeolite obtained from the Semnan area was characterized by X-ray diffraction pattern, FTIR spectroscopy and scanning electron microscopy (SEM). The central composite design (CCD) defin...
