Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

open access: yes, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

Heavy metal distribution between fractions of humic substances in heavily polluted soils

open access: yesPlant, Soil and Environment, 2004
Soil organic matter is important in controlling heavy metal behaviour in soils. This study aims to determine the distribution of organically bound Cd, Pb, and Zn between humic and fulvic acids in 20 samples of heavily polluted Fluvisols.
