Research ArticleOpen accessIn the keywordsThe Application of Electrochemical Impedance Techniques in Analyzing the AC Response of Some Two-electron Transfer Dye SystemsFarouk RashwanThe Electrochemical Impedance Spectroscopic techniques (EIS) were used to investigate the behavior of some dye compounds (quinoid systems) characterized with 2e-transfer processes. For this purpose, Alizarin Red S (ARS), Alizarin Cyanine (AC), Alizarin Viridin (AV) and carminic acid were chosen for the measurements. The EIS experiments were performed using a small AC amplitude (10 mV p-p) in addition to a … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,780 accessesView PDF Cite

Elghuol, Khalilah Abdul Khalil, Mazatulikhma Mat Zain, Mohamed Saifulaman Mohamed SaidNatural products have played a significant role in conventional treatment and in the development of new drugs for a wide range of illnesses, including malignant disease. Urginea maritima is classified as an herb is endemic to the Mediterranean area. This herb was renowned in traditional ethnopharmacological applications. Notwithstanding, there is a lack of evidence pertaining to the characterization of the … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 28 May 2016 · 7,345 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRAPID DEGRADATION OF AZO DYES USING NANO-SCALE ZERO VALENT IRONNabila Rahman, Zainal Abedin, M. Ali HossainIn the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM and … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 8 Apr 2014 · 8,599 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAdsorption Study of Rhodamin B Dye on Iraqi Bentonite and Modified Bentonite by Nanocompounds TIO2, ZNO, AL2O3 and Sodium Dodecyl SulfateIqbal Salman AL-Jobouri, Saadiyah Ahmed Dhahir, Khulood Abed AL-SaadeThe adsorption of Rhodamin B on Iraqi bentonite at the concentration range from 50 to 250 µg mL-1 was studied, Nano compounds; ZnO, TiO2, Al2O3 m and SDS in different amounts 0.01-0.1 g 10-1 g of Bentonite were used to modified the adsorption capacity of bentonite to remove the Rhodamin B from aqueous solutions. The study indicated that using 0.05 … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 7,966 accessesView PDF Cite
