Abstract:

The possibility of determining the anionic surfactant alkylbenzenesulfonic acid by various methods: potentiometric and conductometric titration with sodium hydroxide, conductometric titration with cationic surfactants (tetrabutylammonium bromide, cetyltrimethylammonium bromide) and spectrophotometry in the UV region, was considered. The acid-base titration method allows to determine the alkylbenzenesulfonic acid concentration in pure aqeous solutions. The content of anionic surfactant in the presence of nitric acid can be determined by conductometric titration with cetyltrimethylammonium bromi

Abstract:

This work aims the development and optimization of an alternative method for ranitidine hydrochloride (RAN-HCl) determination. The proposed method was based on conductometric titration of RAN by precipitation of AgCl solid using a solution of AgNO3 as titrant. It was investigated the possibility of performing the titrations on hydroalcoholic and deionized water medium. A limit of detection of 1.0 mmol L-1 and 0.5 mmol L-1 were achieved for RAN titration in deionized water and in a 75:25 hydroalcoholic mixture, respectively. Such behavior is attributed to the dielectric constant of hydroalcohol

Abstract:

Copolymers (HEPP-EG) were synthesized by the condensation of 2-hydroxy-4-ethoxypropiophenone with ethylene glycol in presence of polyphosphoric acid as a catalyst. The copolymers were characterized by elemental analyses, IR spectra, viscosity and thermal studies. The number-average molecular weight (Mn) was measured by non-aqueous conductometric titration. The copolymer HEPP-EG-6 was complexed with metal ions, Cu2+, Ni2+, Co2, Mn2+ and Zn2+ and characterized. Chelation ion-exchange properties have been studied by employing the batch equilibration method.

Abstract:

Thermally stable polymers containing keto–amine–urea groups have been prepared by condensation of keto–amino groups containing diamine and various diisocyanates. The resulting polymer samples have been characterized by elemental analysis and IR spectra, and Mn estimated by non-aqueous conductometric titration and thermogravimetry. Curing of commercial epoxy resin-DGEBA by employing these polymers was scanned on a differential scanning colorimeter (DSC). Glass fibre reinforced composites (i.e. laminates) based on such terpolymer–epoxy resin system have also been prepared and characterized.

Conditions and method for oxidized cotton cellulose obtaining with hemostatic properties have been investigated. Oxidation of cellulose performed by treating of sodium hypochlorite and hydrogen peroxide solutions with various concentrations in different temperature and duration of reaction. Oxidized cellulose samples with different contents of carboxyl groups were obtained. Those samples are characterized by physicochemical methods, as IR-spectroscopy, conductometric titration and optical microscopy. The obtained hemostatic composition was contributed to stopping bleeding from parenchymal orga

Nowadays water-soluble polymers play a significant role in many branches of science and can be used as flocculants for wastewater treatment, as well as biocidal materials for inhibiting the growth of corrosive microorganisms, in particular against sulphate-reducing bacteria. The objects of research are synthesized new polymeric surfactants (poly-surfactants) copolymers of N, N-dimethyl-N, N-diallylammonium chloride with N [(3-trimethylamino) propyl]methacrylamide (DMDAAH TMAPMA). The molar composition and structure of the synthesized copolymers were proved by methods of conductometric titratio
