Determination of Mineral Elements in Plant Tissues Using Trichloroacetic Acid Extraction
نویسندگان
چکیده
An extraction method is described for quantitatively determining Mg, K, Na, 2n, and Mn in plant tissues. The tissue is extracted with 2% trichloroacetic acid and the elements are determined on the filtrate by atomic absorption spectrophotometry. Results compare favorably with those determined after wet ashing with nitric and perchloric acids. In addition, trichloroacetic acid extracts the same fraction of P as does acetic acid and quantitatively extracts total Ca from plant tissues not high in oxalate.
