Allylphenoxypiperidinium Halides As Corrosion Inhibitors Of Carbon Steel And Biocides, Gunay Mehdiyeva Muzakir, Musa Bairamov Rza, Shahnaz Hosseinzadeh Bahador, Gulnara Hasanova Musa
Turkish Journal of Chemistry
A series of 1-(4-(2-allylphenoxy)butyl)piperidin-1-ium halides (4a-d) was synthesized and characterized via spectroscopic methods (FTIR, $^{1}$H NMR). The corrosion inhibition of the synthesized halides on carbon steel in water-salt-hydrocarbon environment, saturated with H$_{2}$S, was investigated. For this purpose, a series of techniques such as gravimetric measurement, potentiodynamic polarisation, and scanning electron microscope (SEM) were used and some thermodynamic parameters of corrosion process ($\Delta G_{ads.}$, $\Delta H^{0}_{ads.}$, $\Delta S^{0}_{ads.})$ were evaluated. The steel surface was checked by SEM, and the steel surface showed good surface coverage. The results showed that the synthesized compounds at the concentrations 125, 150 mg x L$^{-1}$ have …

A Review: A Comparison Of Different Adsorbents For Removal Of Cr (Vi), Cd (Ii) And Ni (Ii), Anja Pfeifer, Mojca Skerget
Turkish Journal of Chemistry
A review of the studies dealing with the removal of chromium, cadmium, and nickel ions with different adsorbents published in the literature between 2014 and 2018 is given in tabular form, along with the adsorption conditions, adsorption isotherm, and kinetic models applied by the authors to model the experimental data and adsorption capacities. The review focuses on the efficiency of ion removal.
