In this study, graphene Th(IV) phosphate was prepared by sol–gel precipitation method. The ion-exchange behavior of this cation-exchanger was studied by investigating properties like ion-exchange capacity for various metal ions, the effect of eluent conce... see more

The membrane-bound sodium–calcium exchanger (NCX) proteins shape Ca2+ homeostasis in many cell types, thus participating in a wide range of physiological and pathological processes. Determination of the crystal structure of an archaeal NCX (NCX_Mj) paved ... see more

Template-free preparation of phillipsite as a novel K+ ion-exchanger was studied systematically by hydrothermal synthesis. The alkalinity, dosage of water glass, dosage of H2O, aging time, reaction temperature and time of hydrothermal synthesis were discu... see more

Pollutants in the air are an ever-present global phenomenon and managing these is a more strenuous task. In expense to higher fuel efficiency in automotive applications, emissions of nitrogen oxides (NOx) are a mounting concern as more demanding emission ... see more

Herein, the removal of divalent heavy metals by two types of zeolites was investigated. The mechanism of cation exchange for Cu2+, Ni2+, Cd2+ and Pb2+ on NaX Faujasite and Linde type A (LTA) zeolites was fully studied. Both zeolites were very efficient in... see more

On the basis of the angrensky coal are received new adsorbents: composite, with the additive in coal of carbonic salts of shchelochno-ground metals for sewage treatment from ions of inorganic impurity and decrease in rigidity of artesian waters; coal heat... see more

In this paper the removal of chromium from Cr/Ca/Mg/K and Cr/Ca/Mg/K/Na solutions was investigated in NaX and NaY packed beds. The breakthrough curves presented some overshooting phenomena where chromium ions displaced the previous exchanged cations. Leng... see more

Isotherm ion exchange of Y zeolite has been studied at different temperatures. The direct exchanges of chromium in NaY show a very high selectivity to the in-going Cr3+ ion. It was also shown that exchange increases with increasing temperature. On the oth... see more
