Total organic carbon and iron forms extracted with sodium dithionite-citrate-bicarbonate (Fed), acid ammonium oxalate (Feo) and sodium pyrophosphate
(Fep) in different systems of land use in Montividiu, Goias.
Sodium Hexameta phosphate (Na6P6O18), Sodium Silicate (Na2SiO3), Sodium Pyrophosphate
(Na2P2O7), and Ethylene-diamine-tetraacetatic-acid (C10H16N2O8) were used as dispersants.
botulinum, the scientists took into account a number of variables, including the effects and interactions of temperature, pH, sodium chloride content, sodium pyrophosphate
and sodium lactate concentration.
Next, add 50 mL of 2% sodium pyrophosphate
to the sand in the beaker.
(98 % purity, lot no 1567 )Acetone ( lot no SC4F540157) and used were purchased from Loba chemicals.
5, 5 mmol/L sodium pyrophosphate
, and 10 mmol/L dithiothreitol (DTT) in a volume of 500 [micro]L.
