Application of response surface methodology (RSM) for experimental optimization in biogenic silica extraction from rice husk and straw ash.

This work aimed to extract silica from combination of rice husk (RH and Rice straw (RS) by optimizing the ash digesting process parameters with the aid of response surface methodology (RSM). The effects of three independent ash digestion process factors like sodium hydroxide concentration (1-3 M), temperature (60-120 °C) and time (1-3 h), for silica production from the mixture of rice husk (RH) and rice straw (RS) were studied. A quadratic model was used to correlate the interaction effects of the independent variables for maximum silica production at the optimum process parameters by employing central composite design (CCD) with RSM.

A critical review on clay-based nanocomposite particles for application of wastewater treatment.

Nanotechnology plays an important function in recent environmental aspects for the elimination of contaminants in the ecosystem. In recent times, nano-clay has initiated more concentration because of its distinctive physicochemical properties and characteristics. Recently, many types of research in clay-based nanocomposite were accomplished in the elimination of pollutants from water sources.

Chromatographic and spectroscopic determination of solvent-extracted leaf oil.

Objective: This study aimed to determine the chemical profile of leaf oil.

Methods: The essential oil was extracted from dried leaf samples using the Soxhlet extraction method. The oil was separated from the solvent and the bioactive compounds were identified using gas chromatography-mass spectroscopy (GC-MS) and Fourier transform infrared spectroscopy (FTIR).

Data set on performance evaluation of discharged wastewater quality from Guna water treatment plant for potable water purpose.

This article provides to evaluate the quality of discharged water from Guna spring water treatment plant and to compare with WHO drinking water standards and Ethiopian bottled drinking water specification to reuse for potable water purpose. The discharged waste water quality analysis was conducted by Physical, Chemical, Biological and Bacteriological parameters of water in association with set of standards. Atomic adsorption spectroscopy (AAS), Flame photometer, UV-Visible spectrometer and Photo meter were used for characterization discharged water.
