J. Liu et B. Deng, SIMULATION CALCULATION FOR CHEMICAL SPECIATION OF PB2-FA-SO42- SYSTEMBY GENETIC ALGORITHMS(), Gaodeng xuexiao huaxue xuebao, 18(10), 1997, pp. 1597-1601
Fulvic acid (FA) has the marked effect on the chemical speciations of
metal ions existed in water system and further affects their biologica
l action as well as their remove and transformation in ecosystem. In t
his paper, the chemical speciation of lead, an important harmful and p
ollution element, in the aqueous solution containing FA and SO42- has
been calculated. The anode stripping current, i, can be measured using
Pb2+ to titrate the aqueous solution containing FA and SO42- by ASV.
According to the chemical model of Pb2+-FA-SO42- constructed basing on
material and chemical balance, the simulation calculation for the che
mical speciations of lead have been made using a novel method of globa
l optimization-genetic algorithm (GA). The results of t test indicate
that there is no significant difference between calculated and experim
ental values of anode stripping current.
