Potassium Dichromate

Potassium Dichromate

Potassium Dichromate

(OP)
We are currently using Potassium Dichromate (inorganic salt) for testing for Organic content in soils as per BS1377:1990.

Does anyone know of a safer alternative to this chemical which has/can be successfully proven to have neglible effects on the test results?

RE: Potassium Dichromate

What is your specific geotechnical need for the percent organic content (not to imply that there is not a need, I'd just like to know the ultimate use of the data in geotechnical application).

RE: Potassium Dichromate

(OP)
Sorry fattdad, not my area of expertise i'm afraid. Organic content does affect shrinkabilty of clays though and can have a detrimental effect on particle size analysis in the lab using the pipette method.
