Synthesis of new azo schiff bases of pyrazole derivatives and their spectroscopic and theoretical investigations
(Elsevier B.V., 2018)
New pyrazole Schiff bases containing azo groups, 4-((E)-phenyldiazenyl)-3-(4-nitrobenzylidene)-1-phenyl-pyrazole-5-amine and its series, were synthesized using the condensation reaction between p-nitrobenzaldehyde and ...
Determination of pKa values of some sulfonamides by LC and LC-PDA methods in acetonitrile-water binary mixtures
(2010)
As constantes de dissociação de sete sulfonamidas antibióticas, sulfadiazina, sulfatiazol, sulfamerazina, sulfametazina, sulfamonometoxina, sulfadoxina e sulfametoxazol, foram determinadas em diferentes misturas binárias ...
Determination of protonation constants of some tetracycline antibiotics by potentiometry and LC methods in water and acetonitrile-water binary mixtures
(2009)
Uma estimativa acurada das constantes de dissociação de antibióticos tetraciclina em misturas binárias acetonitrila-água é muito importante para muitas técnicas de separação, como cromatografia líquida e eletroforese capilar ...
Combined experimental and theoretical investigation of characterization and hydrogen storage properties of Zn(II) based complex and composites
(Elsevier Ltd, 2015)
Metal organic structured coordination complex was synthesized by using Zn(II), 1,10 Phenantroline and teraphtalic acid building blocks. Then the synthesized compound have been characterized with Ft-IR, TGA/DTA/DrTGA, EA, ...
Performance of novel chemical grout in treating sands
(American Society of Civil Engineers (ASCE), 2017)
A new chemical grouting formed by sodium silicate-boric acid mixtures was introduced. Initially, suitable sodium silicate and boric acid contents in the grout mixtures were studied. Gel time, initial viscosity, and syneresis ...
Solvent effect on endosulfan adsorption onto polymeric arginine-methacrylate cryogels
(Springer Verlag, 2018)
Endosulfan is a persistent insecticide that is still used in some countries even though it is life-threatening and banned in the agricultural struggle. The solubility of pesticides in water is negligible. It is known that ...
Use of nicotinamide decorated polymeric cryogels as heavy metal sweeper
(Springer Verlag, 2018)
Cryogels are synthetic polymers used in adsorption experiments in recent years. Because of their macropores, they provide an excellent advantage as an adsorbent in continuous and batch adsorption processes. In this study, ...
Voltammetric behavior and determination of antidepressant drug paroxetine at carbon-based electrodes
(Institute for Ionics, 2015)
Simple, rapid, sensitive, and reproducible methods were developed for the assay of paroxetine in tablets. The electrooxidative behavior and determination of paroxetine on boron-doped diamond and edge plane graphite electrodes ...
Chromate-selective electrodes prepared by using calix[4]arenes for the speciation of Cr(VI) and Cr(III)
(Institute for Ionics, 2017)
The calix[4]arene and its mono-, di-, tri-, and tetra-acryloyl esters were used as suitable ionophores for Cr(VI) species to develop poly(vinyl chloride) (PVC) membrane electrodes. The influence of membrane contents and ...
Removal of DDE by exploiting the alcoho-phobic interactions
(Springer Verlag, 2017)
DDE (1,1-bis-(4-chlorophenyl)-2,2-dichloroethene), which is a commonly used pesticides in agriculture, has harmful effects on human health. Therefore, the removal of this substance from the drinking water and the soil is ...
