in the present work a ph-dependent cloud point extraction procedure using ph-sensitive hydrogel polymer was applied for preconcentration and spectrophotometric determination of the hg(ii) as its thio micher's ketone complex. central composite design (ccd) and response surface method were applied to design the experiments and find out the optimum conditions. four factors entitled concentration o...

Real hospital wastewater was effectively treated by a promising technology based on degradation reaction catalyzed Fe0 under microwave irradiation in this work. powders were synthesized and characterized different techniques, resulting single-phase sample with spherical particles. Optimum experimental conditions determined central composite rotatable design combined response surface methodology...

Hydrometallurgical leaching process has been identified as a viable procedure for recovering metals of value from their matrices. The optimization zinc recovery sphalerite in nitric acid solution was carried out this study. Central Composite Rotatable Design (CCRD) Response Surface Methodology (RSM) and Particle Swarm Optimization (PSO) tool matlab were deployed the studies. RSM modeling gave o...

Abstract This study aimed to develop multicomponent oleogels achieve desirable technological properties, affordability, and enhanced sensory acceptance for future food applications. Two Central Composite Rotatable Designs (CCRD) were performed with three independent variables, monoacylglycerols (MG), candelilla wax (CLX), hardfat (HF). One design used soybean oil (SB) the other high oleic sunfl...

The central composite rotatable design was used to plan the experiments using feed moisture (FM) content, barrel temperature (BT), screw speed (SS), and concentration of Indian horse chestnut flour (IHCF) as process variables varied between 10–18%, 70–150°C, 290–380 rpm 1.75–4.75%, respectively. Surface mechanical energy, water holding capacity, swelling volume, piece density, longitudinal expa...

this paper describes optimization method that combines the plackett-burman design, a factorial design and the response surface method, which were used to optimize the medium for the production of l-asparaginase by serratia marcescens sb08. four medium factors, from out of 11 medium factors, were screened by plackett-burman design experiments and subsequent optimization process to find out the o...

This investigation focuses on the development and optimization of cashew gum polysaccharide (CGP) nanoparticles grafted with polypropylene glycol (PPG) as carriers for diclofenac sodium. The parameters affecting formulation was performed using a central composite rotatable design (CCRD). It demonstrated that best achieved when 10 mg CGP mixed μL PPG homogenized at 22,000 rpm 15 min. physicochem...
