i mean that amino acids are so strong but is there chelating agents which is stronger than them

also it is possible to dissolve barium sulfate by EDTA but is there ant other which is stronger than it to use it ?

check out the chelate effect and the macrocycle effect to see the increase in metal complex stability constants.  some of the best ligands for group 1 and 2 metal ions are crown ethers.
