The focus of the project is new, low cost and simple nature mediated formation silver nanoparticles (Ag-NPs) using leaf extract Anisomeles malabarica. shape size, structure, element composition, functional groups green synthetic Ag-NPs have been studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive (EDX), Fourier Transform Infrared (FTIR), respectively. BET a...

In this paper, chemically synthesized copper oxide nanoparticles (CuO-NPs), were employed for two processes: one is photocatalytic degradation and second one adsorption for the sorption of safranine (SA) dye in an aqueous medium at pH = 12.01. The optimized analytes amount (nano-adsorbent = 0.10 g, conc. range of SA dye 56.13 ppm to 154.37 ppm, pH = 12.01, temperature 303 K) reached to equilibr...

response surface methodology is a common tool in optimizing processes. it mainly concerns situations when there is only one response of interest. however, many designed experiments often involve simultaneous optimization of several quality characteristics. this is called a multiresponse surface optimization problem. a common approach in dealing with these problems is to apply desirability funct...

In this study, ZnO nanoparticles were loaded on activated carbon prepared from almond shell (ZnO-NP-AC). Then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of Basic Blue 41(BB41) and Basic Red 46 (BR46) in binary solution.  The efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...

In this study was developed a natural process using a biological system for the biosynthesis of nanoparticles (NPs) and possible removal of copper from wastewater by dead biomass of the yeast Rhodotorula mucilaginosa. Dead and live biomass of Rhodotorula mucilaginosa was used to analyze the equilibrium and kinetics of copper biosorption by the yeast in function of the initial metal concentratio...

This research presents adsorption potential of surfactant (sodium dodecyl sulphate; SDS) coated magnetite nanoparticles as suitable and efficient adsorbent for the removal of Basic Blue 41 (BB 41), as a cationic dye from textile’s company wastewater. The effects of various experimental parameters (e.g. initial pH of the solution, SDS amount, and ionic strength) on the adsorption efficiency of B...

response surface methodology (rsm) is a statistical method useful in the modeling and analysis of problems in which the response variable receives the influence of several independent variables, in order to determine which are the conditions under which should operate these variables to optimize a corrugated box production process. the purpose of this research is to create response surface mode...

A significant issue for the ecosystem is presence of boron in water resources, particularly produced water. Batch and dynamic experiments were used this research to extract form boric acid from aqueous solutions using selective resins, DIAION CRB05. DIAION™ CRB05 an adsorbent that effective extracting due its high binding capacity selectivity ions, it also regenerable, making cost-effective sus...
