Development of a Quantitative Determination Method for Aluminum Ions in Adsorbed Drugs Using Atomic Absorption Spectrometry with Electrothermal Atomization.

A quantitative determination method for Al in immunobiological drugs using atomic absorption spectroscopy with electrothermal atomization was developed. Conditions for the preparation of aluminum hydroxide gel were selected [NaOH (5 M), heating in a boiling-water bath for 5 min followed by neutralization with conc. HNO].
