Zinc in plant leaves:

Zinc is an essential nutrient in plants and remains distributed in all parts of the plant. About 1g dried plant leaves are grounded with pestle and mortar and dry ashed in silica crucible at 500ºC. The ash is then dissolved within acid and last solution is prepared to 0.1 M HCl. The solution is then directly aspirated into an air-acetylene flame of AAS. A blank is also prepared in exactly similar manner.
