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.

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).
oxides (Figueroa and Mackay 2005; Gu and Karthikeyan 2005), CEC, and pH (Sassman and Lee 2005).
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.
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.
Sao Martinho sugar stocks were up 48 per cent at 227,044 tonnes from a year ago June 30, while anhydrous ethanol stocks were up 106 per cent at 108.64 million liters and hydrous
ethanol stocks up 54 percent at 59.4 million litres.
