Interaction between peat, humic acid and aqueous metal ions

摘要

Analysis of peat samples from four regions of the ritish Isles indicates that the concen- trations of Al, Pb and common transition metals tend, as ecpected, to be higher in regions subject to industrial pollution, but that the concentrations of the non-transitionmetals Na, K, Mg, Ca and Zn tend to be higher in regions remote from industrial pollution. Humci acids were extracted from the most pollution, and least polluted of the peat samples and some characteristics of these acids were compared with those of two commercial acids.
