Optimization of fluoride in water using alum with response surface methodology
Introduction: Fluoride counts an essential element for human health. Therefore, both low and excessive concentrations of that element in drinking water may cause health problems for the consumers. The present study aims to optimize fluoride base in drinking water using Alum response surface methodology. Methods: The present study is an analytical research which uses surface response method b...
متن کاملremediation of cadmium contaminated water by populus nigrasawdust as a low-cost biosorbent: process optimization by using response surface methodology
in this study, the removal of cd(ii) from aqueous solutions have been carried out using populusnigra saw dust as low-cost, readily available biosorbent. various physico-chemical parameters such as ph, initial metal ion concentration, and adsorbent dosage level and contact time were studied at room temperature to optimize the conditions for maximum adsorption. the central composite design was ca...
متن کاملFluoride Levels in Surface and Groundwater in Africa: A Review
Fluoride has been reported to be among natural pollutant of water in Africa. High fluoride levels beyond the recommended World Health Organization limit of 1.5 mg/l has been observed in various Africa countries. However, the information is scattered in different publication medium. Therefore, objective of this work was to put together the information on fluoride levels in surface and groundwate...

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...
