摘要: Abstract Azolla, which is an aquatic fern, has proved to be effective in the uptake and accumulation of metals from polluted waters. Azolla spp., namely A. microphylla cv. MH3 caroliniana Willd, were chosen as model plants so that Cd(II) could accumulated aqueous solution. An increase time concentration solution resulted more both species. Modified Michaelis–Menten equation was employed describe concentration-dependent kinetics through roots MH3, values K m V max found 0.23 mg/L 16.49 μg/(g.f.wt.h), respectively. by occurs partly Ca(II) channels potential mediated Zn(II) transporters.
