New magnetic clays MnFe2O4/Shymkent for removal of heavy metals from wastewater
Baimuratova, Zhaina; Ermekov, Sayat; Silva, Adriano S.; Gomes, Helder; Kalmakhanova, MarzhanThis paper reports the development of a new method. Production of modified clay with magnetic properties based on natural clay from the Shymkent deposit (MnFe2O4/Shymkent nanocomposite), determination of its chemical composition and structure, as well as the study of basic physicochemical properties. The resulting magnetic nanocomposite was then used as an adsorbent to remove nickel (II) ions from wastewater. T...
MnFe2O4/ZHETISAY composite as a novel magnetic material for adsorption of Ni(II)
Baimuratova, Zhaina; Kalmakhanova, Marzhan; Shynazbekova, SH.S.; Kybyraeva, N.S.; Díaz de Tuesta, Jose Luis; Gomes, HelderThis paper deals with the preparation of magnetic adsorbents from natural clays for the adsorption of Ni(II) from aqueous matrices. The phase composition and structure parameters of natural clays and their modified forms, as well as their application as adsorbing agents for the purification of drinking water and their sources were studied. In the study, natural clays from the Zhetisay deposit of Kazakhstan were...
Synthesis and characterization of a new magnetic composite MnFe2O4/clay based o...
Baimuratova, Zhaina; Kalmakhanova, Marzhan; Massalimova, Bakytgul Kabykenovna; Nurlibaeva, A.A.; Kulazhanova, A.S.; Díaz de Tuesta, Jose LuisThe work is devoted to the development of a new method for the synthesis of magnetic composites based on manganese ferrite on a natural clay, coupling with their physico-chemical characterization. In the study, a natural clay of Kazakhstan obtained from the Turkestan deposit was used for the preparation of magnetic composites. The formation of materials with magnetic properties is an urgent task of our time, du...
