Nikkelfrigivelse ved pyritoxidation forårsaget af barometerånding - pumpning
Forklaring
Avs = Fes = 1- Trin
CrS = FeS2 = 2. Trin
Abs. = arbsobans målt ved bølgelængde på 660 mm.
Konc. S2- (ppm) = Abs * udregningsfaktor * fortyndingsfaktor = ppm
Konc. S2- (mg) = Konc. S2- (ppm) * 20ml / 1000 ml/L
Vægt = massen af anvendt sediment
W/W % = konc. S2- (mg) * 100 / vægt * 1000 mg/g
W/W % = summen af AvS og summen af CrS
mmol S2- pr. 100 g sediment = Konc. S2- (mg) * 100g / Vægt * Mw S2-
mmol S2- pr. 100 g sediment = summen af AvS og summen af CrS
mmol S2- pr. 100 g sediment = summen af AvS og CrS
