| Abstract: | Nitric-perchloride acid, 0.5 M hydrochloric acid, 0.05 M EDTA and neutral ammonium acetate were investigated as extractants for copper in peat samples. Greatest contrast between anomalous and background samples was found with nitric-perchloric acid (‘total’) digestion. EDTA or dilute hydrochloric acid liberated 13–100% of the total copper whereas ammonium acetate removed a maximum of 8%. |
