Shale gas can either exist in the free state in natural fractures and intergranular pores, an adsorbed state on organic maceral or clay particle surfaces, or a dissolved state in fluid.
We estimate that coal mine drainage outflows in the Appalachian Basin generate a total of about 538 metric tons of REY per year in a dissolved state, with ~ 83% of that from low pH (< 5) discharges.
Some possible problems may be the maintenance of a low enough pH to keep them protonated and in a dissolved state in brine.
CO2 is primarily transported in a dissolved state in plasma and can be extracted effectively through a membrane lung when connected to high sweep gas flows [4, 5].
Groundwater in BC zone shows unsaturation (−0.33) with respect to the solid phase of CaCO3 (Table 2), indicating a dissolved state, while it is oversaturation (0.48 0.89) in FP and C zones, resulting a precipitated state, which is further supported by the occurrence of CaCO3 concretions in the soil zone due to tropical humid climate of the study region.
Finally, one should mention, that, in a dissolved state, CaPO4 are found in many biological liquids, such as blood serum (Floege et al. 2011), urine (Suller et al. 2005), sweat (Prompt et al. 1978), and milk (Holt 1982) (Lenton et al. 2015) and, therefore, in dairy products (Gaucheron 2012).
In one method, the ore is burned and then reacted with nitric acid to convert uranium into a dissolved state.
It enters drinking-water sources in a dissolved state primarily resulting from the weathering of rocks [ 2].
Cellulose II is formed when native cellulose regenerates from a dissolved state or is mercerized with alkali.
The basic function of lipids is to solubilize the drug and keep it in a dissolved state throughout the transit in the GI tract.
Congress passed the Reconstruction Acts of 1867, dissolving state governments and dividing the South into military districts.
