The iron calibrator that was bound to HEDTA was dissociated from HEDTA under the acidic condition and formed a colored complex with ferrozine.

We also examined the effect of the HEDTA concentration used as a calibrator, which behaved in the same manner as transferrin.
A calibration factor could be generated by the use of HEDTA as a calibrator.
Addition of chelating materials, such as EDTA, HEDTA and EDDHA, to soils is most effective in liberating the labile metal-contaminants into the soil solution.
