Abstract

In the investigation of heavy metals contained in bird feathers, it is important to protect the birds to reduce the amount of material used. However, the investigation of small amounts of feathers has generated difficulties in the techniques of sample preparation. We studied the washing process of the feathers and concluded that ultrasonic washing is efficient enough to eliminate all the water-eliminable contamination from the surface of the feather samples. This study also shows a new way how previous contaminations from the walls of the teflon bomb during the microwave digestion has no effect on the samples taken from the quartz test tubes used by us. There is no loss of the samples, and the memory effect of the bombs is eliminated. We determined the element content from a homogenized feather powder sample of the weight of one swallow feather for Ca, Fe, K, Mg, Mn, Na and Sr, using ICP-AES technique with impulse sample introduction method.
