| Abstract | ||
| A method has been developd determine selenium by hydride generation atomic absorption using nitrogen trapping technique. A series of experiments was performed to obtain the optimum condition. The results show that this method has the advantage of being sensitive, accurate, rapid and simple. Transition metal and other hydride forming elements interferences on the determination of selenium was studied. A substantial increase in the range of interference – free determination of selenium can be achieved by increasing the hydrochloride acid concentration | ||
