Abstract
The aim of this study was to investigate the biodegradable chelating agents S,S-ethylenediaminedisuccinic acid (SS-EDDS) and nitrilotriacetic acid (NTA) as potential alternatives and compare them with ethylenediaminetetraacetic acid (EDTA) for effectiveness. Extraction of heavy metals from chromated copper arsenate (CCA)-treated wood with EDDS, NTA, or EDTA solvent was evaluated at various solvent pH levels and stoichiometric ratios. Based on the present data, the recommended extraction conditions are pH 4.0 and EDDS–CCA stoichiometric ratios of 10.
