In order to ensure the long-term effective isolation of radionuclides from human beings environment, pyrite and magnetite, which exist widely stably in geological can be considered reduce strong mobility high-valence redox-sensitive nuclides low-valence with low mobility. this work, reducing reaction between pyrite, (U, Se, Tc, Np) Gansu proposed-treatment plant area was under simulation by PHR...

Abstract Knowledge of scaling mechanisms and the permeable behavior rocks is highly important for geothermal energy development. In this study, sandstone was soaked in a solution with same chemical composition as water Linyi City, Shandong Province. Permeability tests, scanning electron microscope nuclear magnetic resonance tests were performed on samples after different soak times (0, 30, 60, ...

Abstract Groundwater abstraction wells located in aquifers hydraulically connected with rivers or lakes will induce bank filtration if the water level aquifer is lowered below surface-water level. Many groundwater works utilize this induced infiltration to increase capacity of their wells. Unfortunately, organic-rich surface may alter aquifer’s redox geochemistry, and mobilize iron and/or manga...

In the present study, a total of sixty groundwater samples, twenty each for pre-monsoon, monsoon and post seasons 2018, were collected from selected locations in Mewat district Haryana, India. Electrical conductivity (EC) was measured at site dissolved solids (TDS) estimated. Samples analysed anions (chloride, sulphate, bicarbonate) cations (calcium, potassium, magnesium, sodium). Multiple regr...

Uranium(VI) forms stable Ca-U(VI)-CO3 ternary complexes, which are highly mobile in the environment. This characteristic can be critical as regards radioactive waste disposal deep geological formations. While formation of aqueous complexes has been clearly established and identified under room temperature conditions, effect on their barely investigated. An experimental study was thus designed t...

Abstract The Bundelkhand “giant quartz reef” (BGQR) system comprises 20 major reefs which run for tens of km in strike length average width 40 m and occurs spatial intervals 12–19 the craton, North Central India. BGQR is distinct from vein systems originating crustal scale shearing observed ancient as well modern convergent tectonic settings. Fluid inclusions studied are intriguingly diverse al...

Arsenic (As(V)), a highly toxic metalloid, is known to contaminate wastewater and groundwater difficult degrade in nature. However, the development of efficient adsorbents, at low cost for use practical applications, remains challenging. Thus, investigate As(V) adsorption mechanism, novel porous α-Fe2O3/Fe3O4/C composite (PC-Fe/C-B) was prepared, using bamboo side shoots as bio-template, breakt...

The increasing CO(2) concentration in the Earth's atmosphere, mainly caused by fossil fuel combustion, has led to concerns about global warming. A technology that could possibly contribute to reducing carbon dioxide emissions is the in-situ mineral sequestration (long term geological storage) or the ex-situ mineral sequestration (controlled industrial reactors) of CO(2). In the present study, w...

Abstract The chief source of the oilfield scale is mixing incompatible waters. This study demonstrated that reservoir Mishrif formation (Halfaya oilfield) with six types injection water sources, including Tigris River water, producing formation, Gulf seawater, Marshes Middle Kirkuk and Main Outfall Drain (AL-Masab AL-Aam Channel), leads to salt crusts cause reduction rock permeability. Accordin...

Abstract Temperature is an important factor affecting the leaching of contaminants from waste deposits, especially in Nordic region where temperature change more drastic than other areas. In this study, impact variation sulphate, Co, Fe, Mn, Ni and Zn Ballangen tailings deposit, northern Norway, was investigated using a column experiment. Unoxidized were fed into four columns, which subsequentl...
