“…X-ray phase analysis was performed on the X-ray diffractometer DRON-2. Acidity function of the active centers, prevailing on the surface of the fillers, was determined by potentiometric measurement of рН susp in water with the method that is described in [27]. The studied properties of the oxide fillers are shown in Table 1.…”

“…Using the results of our research, we can propose a technological scheme of sewage treatment on the basis of a natural sorbent -bentonite -in full cycle (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Such a principle scheme for purifying the liquid waste of the galvanic line, or sewage after the tanning of leather production is given in Fig.…”

“…In addition, high maintenance of heavy metal ions prevents the use of water in a number of technological processes. One of the ways to mitigate the environment pollution by wastewater is the application of modern efficient treatment technologies, such as membrane technologies (Goncharuk et al, 2009, Seminska et al, 2016, ultrasound (Starchevskyy et al 2017, Starchevskyy et al 2018, adsorbtion on natural sorbents of mineral (Sabreen et al, 2014, Vasylechko et al, 2003 as well as plant (Danchenko et al 2017) origin, and еlectroextraction (Gomelya et al, 2018) In this regard, the ecologically responsible activity of a modern entrepreneur, which is based on creating a new ecological and economic environment, becomes of particular relevance, provides for the change of existing norms and stereotypes of social and economic activity due to its ecologization, determines the conditions for creating the attractiveness of ecological and economic activity (economic benefits through environmental initiatives, proposals and responsibilities).…”

This work is dedicated to the development of scientific technologies of sewage water clarification of different industrial enterprises from chrome and nickel ions through adsorption by bentonite from Cherkasy field under dynamic conditions. The perspective and efficiency of application of bentonite clays for treatment of sewage water are confirmed by their advantages over other sorbents, that is: they win in accessibility, cost, and possibility of regeneration and multiple usages. The studies proved the expediency of bentonite clays usage for treatment of sewage water from chrome (III), zinc (ІІ) and nickel(II) ions. The static activities were determined and isotherms of adsorption of nickel, zinc and chrome ions were built. Deposition by gravity was chosen as the most optimal method reset of spend sorbent. Dosage of flocculants allows accelerating the process and increasing the degree of deposition. The basic parameters of the precipitation process of the used sorbent were established. The technological schemes of drain water purification from heavy metal ions contamination were developed; in addition to the following sedimentation and regeneration of sorbents.

The influence of regularities of the chemical-mineralogical nature, the dispersity, and the surface properties of inorganic fillers on the protective properties of epoxy polymer composite materials have been investigated. Polymeric compositions based on epoxy resin of ED-20 brand and aliphatic amine curing agent of diethylenetriamine of DETA brand have been chosen as the research materials. The fillers were the air-dry dispersed materials of different nature: oxide, clay and quartz. The resistance of the composites to water and aqueous solutions (absorbency) was investigated by dipping the samples into an aggressive aqueous medium. For the received samples of the filled composites, thermogravimetric (TG) and differential scanning calorimetry (DSC) method were used using the SDT Q600 device manufactured by TA Instruments (USA). It has been found that the thermal stability and the absorbing capacity of the filled composites in water and aqueous acidic and alkaline mediums correlate with each other. It has been shown that to obtain materials with improved protective characteristics, it is necessary to use oxide or clay fillers with the basic (alkaline) surface function.
