Fluoride pollution in groundwater is a major concern in rural areas. The flower petal of Shorea robusta, commonly known as sal tree, is used in the present study both in its native form and Ca-impregnated activated form to eradicate excess fluoride from simulated wastewater. Response surface methodology (RSM) was used for experimental designing and analyzing optimum condition for carbonization vis-à-vis calcium impregnation for preparation of adsorbent. During carbonization, temperature, time and weight ratio of calcium chloride to sal flower petal (SFP) have been considered as input factors and percentage removal of fluoride as response. Optimum condition for carbonization has been obtained as temperature, 500°C; time, 1 h and weight ratio, 2.5 and the sample prepared has been termed as calcium-impregnated carbonized sal flower petal (CCSFP). Optimum condition as analyzed by one-factor-at-a-time (OFAT) method is initial fluoride concentration, 2.91 mg/L; pH 3 and adsorbent dose, 4 g/L. CCSFP shows maximum removal of 98.5% at this condition. RSM has also been used for finding out optimum condition for defluoridation considering initial concentration, pH and adsorbent dose as input parameters.The optimum condition as analyzed by RSM is: initial concentration, 5 mg/L; pH 3.5 and adsorbent dose, 2 g/L. Kinetic and equilibrium data follow Ho pseudo-secondorder kinetic model and Freundlich isotherm model, respectively. Adsorption capacity of CCSFP has been found to be 5.465 mg/g. At optimized condition, CCSFP has been found to remove fluoride (80.4%) efficiently from groundwater collected from Bankura district in West Bengal, a fluoride-contaminated province in India.

“…Box in the 1950s, based on two distinct stages that includes modeling and displacement (Sales et al 2013). The modeling part is usually completed by fitting models, generally linear or quadratic towards factorial designs and augmented factorial designs (Chatterjee et al 2012). It is the combination of statistical and mathematical techniques that is useful for improving and optimizing the batch process, process parameters and determination of mutual interactions.…”

Manganese is important for proper functioning of biological systems, but its deficiency or excess could lead to a number of disorders. Excess amount of Mn(II) can cause neurotoxicity to human beings in terms of a syndrome resembling Parkinson's disease. This study was performed to examine the effect of various operating parameters on percentage of manganese removal from water using zero-valent iron nanoparticles as an adsorbent. A multi-step response surface methodology was applied for the maximum removal of Mn(II) from aqueous solution to optimize the parameters that had an effect on the adsorption studies. A two-level, five factor (2 5 ) full factorial central composite design (CCD) using Design Expert Version 9.0.3 (USA) was used for the optimization. From the CCD design it was observed that the maximum removal of Manganese was 92.5 % obtained at pH 9, temperature 25°C, dose concentration 5 g/L, Mn initial concentration 2.07 g/L for the time period of 6 h. The deviation between the experimental and theoretical result was 0.82 %. Synthesized particles were characterized by scanning electron microscope, X-ray diffraction, and Fourier transform infrared spectra.
