In this study a simple, highly sensitive, and selective electrochemical method was developed for determination of the low concentration curcumin (CUR) using a poly(vanillin-co-caffeic acid) p(Van-CA) modified platinum electrode. Electrode modification was carried out electrochemically with cyclic voltammetry (CV) method. For this purpose; a solution of 6 mM vanillin (Van) and 6 mM caff...

In this work, modification of carbon paste electrode surface with poly (2, 5-Dimethyl aniline) (P-2,5-DMA) by using electrochemical polymerization was described. Then, transition metal ions of Ni(II) were incorporated into the polymer film by two ways. At first way, the polymeric modified electrode was immersed in 0.2 M NiSO4 solutions and the second way was carried out by electrodeposition of ...

The conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. A novel nano-Au/poly (4-aminobenzoicacid) (PABA) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. The PABA film and nano-Au/PABA film were characterized by scanning...

A comparison of the photoefficiency of Ni(II) and NiS incorporated into zeolite P towards photodecolorization of Eriochrome Black T dye solution was investigated in a photocatalytic reactor using UV lamp as a light source. The effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentrati...

lism. Severe changes in the concentration of uric acid causes several diseases such as gout, hyperuricemia and Lesch–Nyhan syndrome. Therefore, the accurate determination of uric acid in urine samples can be a powerful indicator of diagnosing diseases. Thus, many researchers have focused to develop a simple, sensitive and accurate method for determining uric acid. Various methods have been deve...

the electrochemical preparation of poly-n-methylpyrrole (pmpy) coated platinum electrode in chloroform in the presence of tetrabutylammonium perchlorate, hexafluorophosphate, hydrogensulphate, periodate and iodide as supporting electrolytes was performed. the influence of electrosynthesis method, dopant anion type and operation temperature on electrochemical behavior of polymer were demonstrate...

Recently, utilization of biological adsorbents plays an important role in the removal toxic dyes such as Eriochrome Black T (EBT) azo-dye they are considered being produced from natural renewable source, easy availability, low cost, and environmentally friendly. In this study, vermicompost (VC) was utilized to remove aqueous solution along ultrasonic ultrasonic-assisted adsorption. The paramete...
