The Mayuan Zn-Pb deposit on the northern margin of Sichuan Basin is rich in resources. Additionally, a large amount bitumen observed outcrops, and these deposits represent key template for exploring migration hydrocarbon fluids metal elements within an ancient oil reservoir. In this study, chemical experimental method was used to extract adsorbed from chosen five groups samples, mathematical st...

Abstract Most of the world's Zn and Pb is extracted from sediment-hosted Zn-Pb deposits. The deposits hosted in carbonate rocks are hypothesized to form by mixing acidic metal-bearing brines with reduced sulfur-bearing fluids while dissolving sedimentary carbonate. To test role this process, we conducted hydrothermal experiments simulating ore formation reacting ± Ba–bearing H2S SO42– produced ...

A cooperative behavior of Zn(2+) and Li(+) to conduct charges in a Zn-LiFePO4 battery is disclosed. When Li(+) dissolves into the electrolyte, Zn(2+) would deposit, and vice versa. In light of this cooperative behavior, the battery can be viewed as a super hybrid system, which combines the strong points of Zn-air battery, lithium-ion battery and redox-flow cell.

Studies on toxicities and tolerances of cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) in the brown alga Isochrysis galbana and in the green-lipped mussel Perna viridis were conducted by short-term bioassays using endpoints growth production and mortality, respectively. The 5-day EC(50) and 24-h LC(50) of these heavy metals were determined in the brown alga and mussel, respectively. The EC(...

Understanding mechanisms that control plant root metal assimilation in soil is critical to the sustainable management of metal-contaminated land. With the assistance of the synchrotron X-ray fluorescence technique, this study investigated possible mechanisms that control the localization of Fe, Cu, Mn, Pb and Zn in the root tissues of Typha latifolia L. collected from a contaminated wetland. Me...

Heavy metals are widely used in textile industries and significant losses occur during the manufacture and processing of textiles, and these lost heavy metals are discharged in the effluent. Adsorption of heavy metals is a new technology for treatment of wastewater containing different types of selected heavy metals. In this study, adsorbents Carbonized Rice Husk (CRH) and Activated Rice Husk (...

The Weilasituo-bairendaba district is located at the eastern end of Central Asian Orogenic Belt, which an important component Cu-Pb-Zn polymetallic metallogenic belt on Western slope Greater Xing’an Range in Inner Mongolia, China. known Cu-Zn deposits such as Weilasituo deposit and Bairendaba Ag-Pb-Zn are same tectonic-magmatic product. district’s structure framework consists NE-trending region...

Total concentrations and speciation of cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) in surface sediment samples were correlated with the respective metal measured in the total soft tissue of the green-lipped mussel Perna viridis, collected from water off the west coast of Peninsular Malaysia. The aim of this study is to relate the possible differences in the accumulation patterns of the h...

A substantive approach converting waste date pits to mercerized mesoporous date pit activated carbon (DPAC) and utilizing it in the removal of Cd(II), Cu(II), Pb(II), and Zn(II) was reported. In general, rapid heavy metals adsorption kinetics for Co range: 25-100 mg/L was observed, accomplishing 77-97% adsorption within 15 min, finally, attaining equilibrium in 360 min. Linear and non-linear is...
