Uv-Vis, Ir And Xps Analysis Of Uv Induced Changes In Pvc Composites
(Elsevier Science Bv, 1999)
PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ...
Validation Of Spectrophotometric Method To Quantify Veranicline Content In Tablets
(Asian Journal Of Chemistry, 2013)
Varenicline is a nicotinic receptor partial agonist used to treat smoking addiction. The objective of this work was to develope and validate UV-Vis spectrophotometric method for the determination of veranicline in tablets. ...
Development Of An Amperometric Enzyme Electrode Based On Poly(O-Phenylenediamine) For The Determination Of Total Cholesterol In Serum
(Soc Brasileira Quimica, 2012)
A polymer-based amperometric enzyme electrode (Pt/PoPD/ChOx) was prepared for the amperometric detection of free cholesterol. Firstly, poly(o-phenylenediamine) (PoPD) polymer film was prepared in acetonitrile-water medium ...
Effect of Sonic Treatment on The Permeation Performance of Cellulose Acetate Membranes Modified By N-Sio2
(Scientific Technical Research Council Turkey-Tubitak, 2015)
Cellulose acetate (CA) membranes were modified by nano-silicon dioxide (n-SiO2), and they were exposed to ultrasonic waves at a frequency of 35 kHz. The effect of sonication on their water sorption tendency and permeation ...
Determination Of Pk(A) Values Of Some Sulfonamides By Lc And Lc-Pda Methods In Acetonitrile-Water Binary Mixtures
(Soc Brasileira Quimica, 2010)
The dissociation constants of seven sulfonamide antibiotics, sulfadiazine, sulfathiazole, sulfamerazine, sulfamethazine, sulfamonomethoxine, sulfadoxine and sulfamethoxazole, have been determined in different acetonitrile-water ...
Crystal Structure Of 3,3-Dichloro-N-P-Methoxyphenyl-4-(2-Phenylstryl)-2-Azetidinone
(Japan Soc Analytical Chemistry, 2001)
Adsorption Of Mercury(Ii) Ions By Poly(Hydroxyethylmethacryl Ate) Adsorbents With Thiazolidine Groups
(Multi Science Publ Co Ltd, 2002)
A wide variety of adsorbents has been reported in the literature for heavy metal adsorption. We have recently developed a new polymer system for the removal of contaminant heavy metal ions from aquatic systems. Thus, ...
Synthesis of Some Substituted Formazans and Bis Formazans
(Asian Journal Of Chemistry, 2014)
Novel 1-(p-aniinophenyl)-3-(p-substituted -phenyl)-5-phenylforrnazan compounds (2a-f) and 1,1'-(1,1'-biphenyl]-4-4'-yl)bis(3-(p- substituted pheny1)-5-plienylformazan compounds (3a-f) were synthesized by diazo coupling ...
Synthesis of Two Novel Aroyl Thioureas and Their Use as Anion Binding Receptors
(Asian Journal Of Chemistry, 2013)
New aroyl thioureas; N-nicotinoyl-N'-(4-nitrophenyl) thiourea (3a) and N-nicotinoyl-N'-(2-nitrophenyl) thiourea (3b) were synthesized and studied as anion-binding receptors. Upon adding tetrabutyl ammonium halides (fluoride, ...
The Effect Of Hydrogen Bonding On The Electroreduction Behavior Of Aminobenzimidazoles
(Slovensko Kemijsko Drustvo, 2004)
The electroreductions of benzimidazole, 5-aminobenzimidazole, 2-aminobenzimidazole and 4-aminobenzimidazole were investigated on a Pt electrode in acetonitrile containing tetrafluoroborat (TBABF(4)) with and without the ...
