Disposing of waste chemicals in set cocrete?

[hippacrocadillapig]

Would the following chemicals be safely disposed of when used as water to mix with cement and aggregate to make concrete?
Nitric Acid S.G. 1.4 (10ml)
0.1 mol Silver Nitrate Solution (20-25ml)
0.1 mol Potassium Thiocyanate Solution (20-25ml)
Ammonium Ferric Sulphate (1ml)
3,5,5 Trimethyhexanol (2ml)
N.B. These chemicals are used in a Chloride ion titration test for concrete. The amounts used per test are in parentheses.

Where are you located? What really matters are the environmental laws applicable to your location and not what is believed to be "safe". In the U.S., this material would be a hazardous waste and at a minimum would be subject to RCRA laws and any other state, local
laws that are relevant.

hippa, Some of thes compounds youre talking about are classified as Hazardous wastes and undoubtedly fall under your State Haz. waste regulations as well as RCRA. As such they cannot be just willy-nilly disposed of. Due to the small quantities involved, they can be classified as a "lab-pak" and then disposed of at an approved TSDF (Treatment Storage Disposal Facility) all at a minimal cost. This will guarantee that you disposing of these materials in an environmentally acceptable manner, not too mention fullfilling all of your obligations under the law ( I take it you don't look good in stripes).

Here are a few TSDF's that you can contact:

Heritage Environmental Services
SET Environmental Inc.
Clean Harbors
Pollution Control Industries
Safety Kleen Corp.

Good luck!
