TAPS (buffer)
TAPS is a chemical compound commonly used to make buffer solutions.
It can bind divalent cations, including Co and Ni.
TAPS is effective to make buffer solutions in the pH range 7.7–9.1, since it has a pKa value of 8.44 .
The pH of the buffer solution changes with concentration and temperature, and this effect may be predicted e.g. using online calculators.
