Struvite may not be a household word, but it is all too familiar to the operators of wastewater treatment plants.A crystalline mineral known chemically as magnesium ammonium phosphate hexahydrate, str...
2017年3月15日,《Water Research》上刊发了中国地质大学生物地质与环境地质国家重点实验室朱健博士的论文——碳酸钙诱导模拟酸性矿山废水pH升高引起Fe(II)氧化活化氧气产生羟自由基(Production of hydroxyl radicals from oxygenation of simulated AMD due to CaCO3-induced pH increase)。
This workshop targets operational petroleum geochemistry in carbonate reservoirs. The goal is to provide a perspective on how established and emerging geochemical tools can help to have a comprehensiv...
To ascertain factors controlling melt production along a typical distal, ‘hotspot-interacting’ mid-ocean ridge, we investigated the extent and distribution of both plume-related and plume-unrelated b...
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand shows that rock can transform into soil more than twice as fast as previously believed possible. ...
Understanding the source and chemical characteristics of groundwater used for sake production is an important strategy for the quality management of sake brewing. Oxygen isotope ratios (δ18O) of 96 s...
Estimation of 26Al (half-life = 705 kyr) content at the time of meteorite fall is required to calculate the terrestrial age of meteorites using the 26Al content. Previous studies (e.g., Cressy, 1971;...
A mathematical model capable of providing a forecast of future consumption and import of natural gas is essential for the planning of the Brazilian energy matrix. The aim of this study is to compare t...
Pore waters were taken from core sediments of Sites C0001, C0004, and C0008 on the landward slope of the Nankai Trough and Site C0002 in the forearc basin of the Nankai accretionary prism off Kumano ...
Bacteria were investigated for the production of methyl chloride, methyl bromide, and methyl iodide from brackish water. Bacteria were isolated and incubated at 25uC, and the concentrations of methyl...
Carmeuse North America crushes over 14 million tons per year of limestone and dolomite for the production of lime in North America. The cost of crushing the stone is the single largest consumer of en...
This study investigates the ability of the unicellular green alga Nannochloris atomus to precipitate CaCO3, quantifies mineral precipitation rates, estimates sediment production in a N. atomusbloom, a...
Montmorillonite-based catalysts were compared with an acidic ion-exchange resin of the type used industrially for the production of methyl t-butyl ether (MTBE) from methanol and isobutene or t-butanol...
