Use of densimetric techniques for fractionating soil organic constituents [PDF]

, 1967
Ultrasonic dispersion of soil was used as a pretreatment, prior to densimetric fractionation in a heavy liquid. A 2 to 3 minute sanification period, using a probe type instrument with a 125 watts power output, resulted in maximum recoveries of ...

Aromacity of coal - a reappraisal of the graphical densimetric approach

, 1988
A reappraisal of the graphical-densimetric approach has clearly indicated that values of aromaticity (fa) originally derived thereof, are in reality about 10–15% higher, especially in the lower rank coals (C: 70.5 to 81.5%), for several reasons e.g., (i)

Role of natural nanoparticles on the speciation of Ni in andosols of la Reunion

, 2009
Andosols on the island of Reunion have high nickel (Ni) concentrations due to the natural pedo-geochemical background. Enhanced knowledge of Ni speciation is necessary to predict the bioavailability and potential toxicity of this element.

Densimetric separation of coarse aggregates and fine quartz fraction in recycled concrete aggregates using the jigging process

Except for a few specific use cases, such as historical restoration and building maintenance, most unusable buildings, streets, highways, bridges, dams, etc., are demolished. In Europe, between 350 and 700 million tons of construction and demolition waste (CDW) are generated annually, generating environmental liabilities from its disposal, as well as ...

Can secular stable soil organic carbon be isolated? An assessment of Zimmermann fractionation using a long-term bare fallow

International audienceThe “42 plots of Versailles” site is a long-term bare fallow established in 1928. Over the course of almost 100 years, these plots have been carefully maintained without vegetation and enriched annually with various fertilizers and ...
