Looking for a database, containing selected complexing agents

(1/1)

chartman:
Dear Sir or Madam,

for performing a batch experiment to extract metal(loid)s from a solid phase, I would like to make a buffered stock solution. I am using different salts of complexing agents as solvents (Methylglycinediacetic acid trisodium salt, polyaspartic acid sodium salt, sodium diethyldithiocarbamate). I am aiming for determining the pH as well as the buffer capacity of the stock solution, containing one above-mentioned salt and a suitable acid.

My question is: Is there any database which already contains the thermodynamic data for these complexing agents? If not, which data do I need to define these species?

I would be very grateful for an answer. Many thanks in advance!

Warm regards,
chartman

I do not know of a database with any of those salts.
