REMOVAL OF AMMONIA FROM DISTILLERY WASTE-WATER BY ION EXCHANGE
Abstract: This paper evaluates the removal of ammonium ions from wastewater and its subsequent treatment. The project is based upon a case study of a local distillery facing a problem of odor and wastewater disposal management because of the presence of high concentrations of ammonia, for which ion exchange principal for treatment was employed. Ion exchange has the ability to handle shock loadings and the treated water can be recycled again …

Nanocomposites Based on LDPE–EVA Thermoplastic Elastomer (TPE): Effect of Laponite Clay
Abstract: The effect of pristine and modified laponite RD and RDS on a model low-density polyethylene (LDPE)—ethylene vinyl acetate copolymer (EVA) thermoplastic elastomer (TPE) blend system is explored in this article. The nanoclay particles are melt-blended with the LDPE–EVA system at 1.5 wt% loading. Both laponite RD and RDS are modified by ion exchange method utilizing dodecyl ammonium ion to improve the interaction of clay particles with polymer matrix. The blends …

Development and Evaluation of a Novel Polyaniline/Polyvinyl Alcohol/Silver Nanocomposite for Antibacterial Applications: Synthesis and Characterization
Abstract: A novel nanocomposite made up of polyaniline, polyvinyl alcohol, and silver (PAL/PVA/Ag) was synthesized using the reduction of chemical technique in this study. Aniline was polymerized in situ with ammonium persulfate to create polyaniline (PAL), while Ag+ ions were employed to make an nanoparticle of Ag colloidal solution. The combination of Ag nanoparticles with the PAL/PVA composite resulted in the development of a new nanocomposite. Scanning electron microscopy (SEM) and …

Determination of Gatifloxacin in Human Urine by Liquid Chromatography-Tandem Mass Spectrometry
Abstract: Gatifloxacin (GTF) is an antibiotic of the fourth-generation fluoroquinolone family that inhibits the bacterial enzymes DNA gyrase and topoisomerase IV. A reliable, sensitive and selective isocratic reversed phase liquid chromatographic-tandem mass spectrometric (LC-MS-MS) method was developed to determine gatifloxacin (GTF) in human urine. GTF, in urine after solid-phase extraction with SPE cartridge, was analyzed on a C18 column (Symmetric 3.5 μm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem …

Effect of ZrO2 nanoparticles on Electrical conductivity of PVA/PVP polymer blend doped with ammonium iodide
Abstract: This work reports the properties of solid polymer electrolyte films obtained via incorporating varying amounts of ZrO2 nanoparticles into the PVA/PVP polymer blend with ammonium iodide salt. Material synthesis was done by the solution casting technique. Frequency dependent impedance and conductivity parameters of polymer electrolyte films were investigated at different temperatures (303K-353K) using impedance spectroscopy. The results of ionic conductivity of prepared polymer blend samples at various temperatures were studied …

Analysis of Anti-psychotic Drug Penfluridol in Human Plasma by HPLC and MS/MS
Abstract: Penfluridol is a new long-acting neuroleptic drug known to be used widely for treating psychotic conditions. An internal standard was employed, which was penfluridol D7 (IS). The analyte and the IS were separated on a Phenomenex Kinetex C18, 5µm 100A, 100*4.6mm column using acetonitrile (40:60, v/v) as the mobile phase and 5 mM ammonium formate as the stationary phase. The retention time of Penfluridol and Penfluridol d7 was set at …

Growth and Studies of Strontium Chloride Doped Ammonium Dihydrogen Phosphate Crystals
Abstract: Single crystals of undoped ammonium dihydrogen phosphate (ADP) and strontium chloride doped ammonium dihydrogen phosphate were grown by a solution method. It is found that SCADP crystal belongs to the tetragonal crystal system with I-42d space group. It is seen that both undoped and strontium chloride doped ADP crystals crystallize in the same tetragonal system and the incorporation of dopant does not alter the crystal system. This is due to …
