Murphy and Riley's colorimetric methods are suitable for alkaline samples. For sediment extracted with strong acids (pH of the supernatant is 0.8-5), what method and solution are suitable for colorimetry?
I respectfully correct your statement the Murphy and Riley is suitable for alkaline solutions: the reaction occurs under acidic conditions
@ Mina, I think you may use Bray,s method .
Yes, better use Brays method...
