Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...

Effects of Wet Grinding Process on the Properties of the Ground Diatomite Particles
Adsorption Diatomite Grinding Time Wet Grinding
2011/11/14
Wet grinding of diatomite was carried out in a stirred mill. The changes in particle size, specific surface area and structure or the particle shape in the wet grinding process were investigated. The ...
Role of colloidal particles for hydrogeochemistry in As-affected aquifers of the Hetao Basin, Inner Mongolia
aqueous geochemistry arsenic colloid shallow groundwater
2017/8/9
High As groundwater was found in shallow aquifers of the Hetao Basin, Inner Mongolia, which has caused serious chronic arsenism. Groundwater particles are ubiquitous in natural aquifers, and significa...
