Thus, the andesite appears to have been derived by partial melting of
hydrous mafic crust under moderate to low pressure (<8 kbar).
The sequential extraction procedure, applied to Fe-As (V) samples exchanged with arsenate, showed that the As (V) specifically sorbed associated with amorphous crystalline
hydrous oxides of Fe were the dominant species (over 90%) from the Fe-As (V) samples in different dosing modes.
Hydrous pyrolysis of shale and berries was carried out in pyrolysis conditions at which the maximum yield of soluble pyrolysis product was achieved (duration two hours and pyrolysis temperature 380 [degrees]C for shale, and 340 [degrees]C for berries).
2004),
hydrous oxides (Figueroa and Mackay 2005; Gu and Karthikeyan 2005), CEC, and pH (Sassman and Lee 2005).
Hydrous ASP products for global specialty markets will be increased $20 per short ton, Satintone and Ultrex calcined grades $30 per short ton and Translink surface-treated grades $34 per short ton, effective with shipment on and after Oct.
A
hydrous iron sulfate (determined by SEM-EDS) was noted in minute amounts, on a single specimen, as orange-red prismatic microcrystals.
These results bolster findings obtained by Lewan and complement research in
hydrous pyrolysis by providing some details about the chemistry that could be occurring during these transformations.
Product mix also includes sale of
hydrous, anhydrous and industrial ethanol.
