This article raises the relevancy problems of bimetallic nanostructures using to inhibit corrosion processes specific to various sulfur-containing media, including the extraction and transportation of natural hydrocarbons, in oil and gas condensate equipment. The environmental aspect of the research is the possibility of using bimetallic nanostructures modified with cysteine as environmentally friendly agents that protect steel from corrosion, especially in a thiol medium. There are presented experimental data on the synthesis and study of bimetallic nanostructures based on copper and silver in a thiol medium based on cysteine aminoacid. The research field is conditioned by these days' tendency that advanced developments in many branches of science are directly associated to the application of nanomaterials. The high action efficiency of these materials is achieved due to their highly dispersed state, distinguishing them favorably from conventional macroobjects. The synthesis of Cu/Ag nanostructures was carried out due to the unique properties of bimetals, such as increased activity of atoms in the surface layer, display of quantum effects, etc., that are more pronounced than those in monometallic nanostructures. The main article concept lies within simulation the process of sulfides and other sulfur compounds formation with bimetallic nanoparticles to protect oil and gas equipment from sulfur-containing corrosive agents in aqueous medium. The goal is to synthesize the copper-silver bimetallic microparticles stabilized with apple pectin and verification of the possibility of forming a metal-sulfur bond at the nanoscale level with cysteine aminoacid as a suitable and convenient compound. The objectives include directly the method of synthesis of the bimetallic microstructure Cu-Ag, stabilized with a solution of apple pectin; absorption spectrophotometry of the studied disperse system of bimetallic Cu-Ag microparticles in the visible region; scanning electron microscopy (SEM) of the bimetallic Cu-Ag microparticles obtained; study of chemisorption of L-cysteine hydrochloride on the dispersed phase surface of bimetallic Cu-Ag microparticles; Raman-scattering spectroscopy of the sample obtained after chemisorption.

Bentonitic clay and wood sawdust are natural materials widely available in nature at low cost with high heavy metals sorption properties that, in this work, were combined to achieve an effective composite biosorbent with high sorption properties and enhanced mechanical stability. Pine, aspen, and birch wood sawdust, as well as different bentonite clays and different sawdust modification methods (H3PO4 or HCl) were used for preparing new composite biosorbents. A mixture of wood sawdust and bentonite in a ratio of 2:1 was used. All materials were characterized by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscope (SEM) methods and tested for Cu and Ni ions removal from water. The adsorption process for all composite biosorbents was well described from a pseudo-second order kinetic model (R2 > 0.9999) with a very high initial adsorption rate of Cu and Ni ions and a maximum uptake recorded within 2 h. The results have shown that the adsorption capacity depends mainly on the kind of wood and the acid treatment of the wood that enhances the adsorption capacity. At a concentration of 50 mg/L, the biosorbent prepared using birch wood sawdust showed the worst performance, removing barely 30% of Cu and Ni ions, while aspen wood sawdust improved the adsorption of Cu (88.6%) and Ni (52.4%) ions. Finally, composite biosorbent with pine wood sawdust showed the best adsorption be haviour with an efficiency removal of 98.2 and 96.3% of Cu and Ni ions, respectively, making it a good candidate as an inexpensive and effective biosorbent for the removal of heavy metals.

“…Consequently, there is a need to modify the original raw material before its practical use. It is known that the synthesis of bentonite clay with high sorption capacity efficiently absorbs different metal ions from wastewater [Mamyachenkov et al, 2017]. When bentonite clays and shungites of East Kazakhstan deposits were studied, the following advantages were defined: high sorption properties; low cost (in comparison with the reagents used in water purification technology); temperature and climatic conditions resistance during haulage, storage and operation.…”

This work is devoted to mine wastewater purification from metal ions, such as copper, zinc, lead, cadmium, iron, and manganese. The rationale was provided for the possibility to purify the wastewater from metal ions with nonactivated and ultra-dispersed natural sorbents. The adsorption capacity of bentonite clay from Tagan deposit and shungite from Koksui deposit of the Republic of Kazakhstan was studied on the basis of its fraction composition. It was found that the most effective method of sorbents modification was mechanical activation. The comparative studies of metal ions adsorption efficiency were carried out with mechanically activated and ultra-dispersed bentonite clay and shungite. The experiment enabled to find out that ultra-dispersed bentonite clay is prospective for use in order to deeply purify multicomponent mine wastewater. The highest degree of metal ions extraction was achieved due to 30-minutes contact of wastewater.
