- Adsorption of phenol contains water and wastewater.
- Chemical toxicity of phenol affects the air, water, and soil.
- Operating parameters optimization with response surface methodology (RSM).
- Saw dust as bio-adsorbent material.
- Physicochemical characteristics of activated sawdust.
Organic pollutants have an adverse effect on the neighboring environment. Industrial activates are the major sources of different organic pollutants. These primary pollutants react with surrounding and forms secondary pollutant, which persists for a long time. The present investigation has been carried out on the surface of activated sawdust for phenol eliminations. The process parameters initial concentration, contact time, adsorbent dose and pH were optimized by the response surface methodology (RSM). The numerical optimization of sawdust (SD), initial concentration 10Â mg/l, contact time 1.5Â h, adsorbent dose 4Â g and pH 2, the optimum response result was 78.3% adsorption. Analysis of variance (ANOVA) was used to judge the adequacy of the central composite design and quadratic model found to be suitable. The coefficient of determination values was found to be maximum Adj R2 0.7223, and Pre R2 0.5739 and significant regression at 95% confidence level values.
