Constructing ethanol-derived bioactive extracts using the brown seaweed Zonaria tournefortii (J.V.Lamouroux) Montagne performed with Timatic extractor by means of response surface methodology (RSM)

Design of Dye Adsorption by Amine Terminated Dendritic Functionalized Halloysite Nanotubes Using Response Surface Methodology (RSM)

Photocatalytic degradation of rhodamine B by nano bismuth oxide: Process modeling by response surface methodology (RSM)

The photocatalytic activity of nano-Bi2O3 was evaluated in degradation of rhodamine B (RhB) as a model of dye pollutant from waste waters. Nano sized Bi2O3 was synthesized using the chemical precipitation method. The as-prepared sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spect...

Synergistic effects of Iranian seaweed compounds for anticandidal properties and optimization by Response Surface Methodology

An optimization procedure was applied to investigate the anticandidal property of four different Iranian seaweed extract compositions. Response Surface Methodology (RSM) with the four levels- three–factor Box–Behnken design, including Gracilaria arquata concentration (X1), Nizimudidnia zanardini concentration (X2), Cystoceria indica concentration (X3) and Padina australis concentration (X4), wa...

Investigation of UV/TiO2-N photocatalytic degradation of AR 40 using response surface methodology (RSM)

Introduction: Advanced oxidation processes (AOPs) suggest a highly reactive, nonspecific oxidant namely hydroxyl radical (OH•), that oxidize a wide range of pollutants fast and non-selective in wastewater and water. Materials and methods: In this work, the nitrogen-doped titanium dioxide nanoparticles were primed by sol-gel method, characterized by X-ray diffraction and Scanning Elect...
