IODINE-HUMIC COMPLEXESIODINE-FULVIC COMPLEXESSANDNatural organic carbon is believed to enhance the transport of associated contaminants through the geosphere and it is important to understand the migration behaviour of natural organic compounds. The stability and mobility of 125 I labelled humic and ...
Metal-humic complexes are typical and important species because humic and fulvic acids dominate naturally occurring organic matter in fresh water. This article... HIRAIDE,Masataka - 《Analytical Sciences》 被引量: 123发表: 1992年 Trace humic and fulvic acid determination in natural water by cloud ...
The results show that site and electrostatic competition are the major mechanisms explaining the effects of natural organic matter on the arsenic speciation, whereas other possible mechanisms, such as a chemical reduction of arsenate to arsenite and formation of ternary organic arsenic complexes, are ...
complexation of Cu 2+ ions in illite–FA bi-complexant systems by taking it to be an additive complexation of two mono-complexant systems (FA–Cu 2+ and illite–Cu 2+ ) and (iii) FA can inhibit the retention of heavy metals at solid surfaces by forming soluble complexes with metal ...
Neither percentage extractable carbon nor Cf/C clearly differentiated between Bm and Ah horizons.Ratios of Al + Fe to fulvic acid in the extracts of the B horizons were as high as or higher than those of some insoluble synthetic complexes. 展开 ...
humic acidfulvic acidHarmattan dustnorthern Nigeriaorganic complexesHumic acid and fulvic acid were extracted from Harmattan dust. The dust contains 0.47% humic acid, 0.14% fulvic acid and 99.39% humin. Electron spin resonance was combined with chemical treatment to obtain information on oxidation ...
