A complexometric method based on sele ctive masking and de-masking has been developed for the rapid determinatio n of aluminium, lead and zinc from the same solution in glass and glass frit samples. The determination is carr ied out using potassium cya nide to mask zinc, and excess disodium salt of EDTA to mask lead an d aluminium. The excess EDTA was titrated with standard Mn(II)SO 4 solution using Erichrome Black-T as the indicator. Subseque ntly selective de- masking agents – triethanolamine, 2,3-dimercapto propanol and a formaldehyde/acetone mixture – were used to determine quantities of aluminium, lead and zinc in a stepwise and selective manner
