[ 1 ] - Kinetic investigation of photocatalytic degradation of dimethyldisulfide by zeolite A containing nano CdS
In this research, zeolite A was synthesized from waste porcelain and CdS nano-particles were doped in zeolite framework by a precipitation after an ion exchanging process. All raw and modified samples were characterized by FT-IR, XRD and SEM methods. Primary experiments showed that the good efficiency of loaded nano CdS onto the zeolite A for photodecomposition of dimethyldisulfide (DMDS) under...
[ 2 ] - A comparison between the heterogeneous photodecolorization of an azo dye using Ni/P zeolite and NiS/P zeolite catalysts
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...

[ 5 ] - Least-squares support vector machine and its application in the simultaneous quantitative spectrophotometric determination of pharmaceutical ternary mixture
This paper proposes the least-squares support vector machine (LS-SVM) as an intelligent method applied on absorption spectra for the simultaneous determination of paracetamol (PCT), caffeine (CAF) and ibuprofen (IB) in Novafen. The signal to noise ratio (S/N) increased. Also, In the LS - SVM model, Kernel parameter (σ2) and capacity factor (C) were optimized. Excellent prediction was shown usin...
