Still, if Ivanov's hoped-for human trials pan out, a syringe of EDTA may one day join that space blanket in your winter survival kit. |
That represents fairly considerable progress, because in the main these substances are PCBs, free cyanide, EDTA, dioxins and bisphenols. |
When EDTA chelates the ions, the solution changes to the blue color of the indicator in alkaline solution. |
However, EDTA is not ideal because it also binds essential divalent cations such as calcium and zinc. |
If the complexing agent EDTA is used as titrant instead of EGTA, the sum of calcium and magnesium is obtained. |
Immediately after collecting the blood invert each tube several times to mix the EDTA and blood. |
