EDTA Extractable Arsenic in Relation to Available Forms in Soil
Lee, C. K. and Low, K. S. (1990) EDTA Extractable Arsenic in Relation to Available Forms in Soil. Pertanika, 13 (2). pp. 261-265.
Ten soil smaples from cocoa estates were extracted with 10 m MEDTA solution at a soil/solution weight ratio of 1/25. Arsenic in the extract was determined by hydride generation inductively coupled plasma atomic emission spectrometry. EDTA extractable arsenic showed significant positive correlation with Al-As, Fe-As, and arsenic extracted by the methods of Mehlich I and III, Bray PI and Olsen.
