This book focuses on the important binding properties of these compounds which regulate the chemical reactivity and bioavailability of hydrogen and metal ions in the natural environment. Topics covered include the physico-chemical properties of humic matter and interactions of protons and metal cations with weak acids and macromolecules. Experimental laboratory methods are also discussed, together with mathematical modelling. Finally the author looks at how the results of this research can be used to interpret environmental phenomena in soils, waters and sediments. This comprehensive account of cation binding by humic matter is a valuable resource for advanced undergraduate and graduate students, environmental scientists, ecologists and geochemists. 410 0$aCambridge environmental chemistry series ;$v12. 606 $aHumic acid$xDerivatives 606 $aCations 606 $aLigand binding (Biochemistry)$xMathematical models 615 0$aHumic acid$xDerivatives. 615 0$aCations. 615 0$aLigand binding (Biochemistry)$xMathematical models. 676 $a572/.33 700 $aTipping$b Edward$f1948-$01051218 801 0$bUkCbUP 801 1$bUkCbUP 906 $aBOOK 912 $a9910449784903321 996 $aCation binding by humic substances$92481570 997 $aUNINA
