In this research, a glassy carbon electrode was coated with a thin layer of multi-walled carbon nanotubes in the presence of the surfactant and subsequently was electro-polymerized with Poly-L-arginine (P-L-Arg). The prepared electrode was used as an effective sensor for the quantitative detection of Rutin (Ru). The fabricated electrode exhibited good electrochemical performance with low electr...

Enzyme modified electrodes were fabricated with poly(aniline-co-maminophenol). Electrochemical polymerization of aniline and m-aminophenol was performed to get the film of copolymer on the surface of gold electrode. Modified electrodes were fabricated by two methods, physical entrapment and covalent cross-linking. In one of the method, gold nanoparticles were loaded into the copolymer film and ...

The present study deals with the adsorption of Bromophenol blue (BB) and Erichrome black T (EBT) – two anionic dyes – onto bentonite carbon composite material (BCC). Batch studies were performed to evaluate the influence of various experimental parameters such as: pH, contact time, adsorbent dose and initial dye concentration. The optimal conditions for the dyes removal were found to be at pH =...

An all-printed photosensor based on polyfluorene derivatives has been developed for high illuminance range detection (>100 klux). The active layer is a blend of hole-accepting poly(9,9’-dioctylfluorene-cobis-N,N’-(4-butylphenyl)-bis-N,N’-phenyl-1,4-phenylenediamine) (PFB) and electron-accepting poly(9,9’-dioctylfluorene-co-benzothiadiazole) (F8BT). A top-absorbing architecture was used with pol...

In the present work, adsorption behavior of Eriochrome Black T (EBT) on waste hemp activated carbon (WHAC) was examined. The surface WHAC modified by H3PO4 acid treatment. and structural characterization adsorbents carried out using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) analysis. effect influential parameters (pH, contact time, dosage, initial concen...

A simple approach to prepare and characterize biomaterial-based electrocatalysts for oxygen reduction was carried out. Poly-l-histidine was used as a matrix and ligand to complex Cu2+ to mimic the active sites of laccases. A modified glassy carbon (GC) electrode with Cu2+-poly-l-histidine complex decreases the oxygen reduction overpotential as compared with the bare GC electrode. An array of Cu...

The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....

In this paper, multi-wall carbon nanotubes (MWCNTs), gold nanoparticles (GNp) and glucose oxidase (GOD) was developed for the specific detection of glucose. MWCNTs were chemically modified with the H2SO4–HNO3 pretreatment to introduce carboxyl groups which were used to interact with the amino groups of poly(allylamine) (PAA) and cysteamine via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hy...
