| Abstract | ||
| A microgram amount of Organo iron and iron containing drug were decomposed using Schoniger flask combustion technique using a Pyrex- glass spiral as a sample holder. A 10mg of solid sodium sulphite was mixed with the weighed sample before the combustion step , 10ml of 5N- hydrochloric acid was used as absorbent solution, and 1ml of 20% perchloric acid was added to the resulting solution prior to the boiling step. The iron content was finally determined using atomic absorption spectrophotometer at wave length (248.3nm) with the help of a calibration graph prepared from standard solutions of ferric chloride. The percentage error were ranging from – 0.28 to + 0.35%, and the percent standard deviation was (0.869).` | ||
