Test Method for Ethylene Diamine Tetraacetate (EDTA) in Soaps or Synthetic Detergents

A survey was made of the extractive power of 15 reagents for organic matter from the A0 and B21 horizons of a podzol. All were inorganic except disodium ethylene diamine tetraacetate (EDTA-Na2) and their solutions ranged in pH from 1.4 to 13.1. The amount of organic matter extracted varied with horizon and with extractant. While only NaOH removed appreciable amounts from the A0 horizon, Na4P2O7, Na3PO4, NaF, Na2CO3, NaOH, HF and EDTA-Na2 extracted > 80 per cent of the organic matter of the B21 horizon. No organic matter from the A0 horizon extracts passed through a cellulose membrane on dialysis against distilled water whereas the B21 extracts lost from 20 to 70 per cent of their carbon content. The ash content of the non-dialyzable portion of the B21 horizon extracts was high (20–40 per cent), indicating the possible presence of complexes of organic matter with metals such as Fe and Al and with clays. The carbon contents of the same materials ranged between 40 and 50 per cent, suggesting that all extractants removed essentially a similar type of material.
