Removal Of Fluoride Ions From Drinking Water Using Organic Matrix “OM” (Date Seeds-Deglet Nour) : Analyze The Effect Of Experimental Conditions

Abstract

The  purpose  of  this  study  is  to  D´efluoruration  of  groundwater  in the region of Ouargla south-east Algeria whose concentration of fluoride ions increased more than 2.78 mg/l that exceeded WHO standards. Procedure in- volves adsorption of organic matrix were prepared from a new lignocellulosic biomass source: date seeds without the addition of any chemicals and analyze the effect of experimental conditions (contact time -temperature- granular di- ameter diversity -PH- adsorption dose) in enhancing the adsorption capacity of fluoride ions The best results were conducted using spectrophotometer type DR 6000, (λ = 580nm) The effect of the reaction time was observed from 5 to 1440 minutes, temperature and adsorption dose between raw water and the organic matrix. Indicated a maximum removal percentage (98.56 %) with an initial concentration of F ions 2.78 mg/l and the fluoride removal temperature appeared to be between 105–400 °C was 200 m, 60 min, 6 and 1 g/40 mL, respectively, may be used of organic matrix as sustainable, low-cost and efficient adsorbents for F- removal from aqueous solution. Overall, the results conducted in the present research indicated that the water treatment in the region of Ouargla may favorably affect the water availability, lifestyle and Public health of the population in this Saharan region.
