Removal of Fe (III), Mn (II) and Zn (II) from palm oil mill effluent
— Highlights We removed Fe(III), Zn(II) and Mn(II) ions by natural zeolite from palm oil mill effluent (POME). Percentage of metallic ions removal by natural zeolite was ∼65% for Fe, ∼52% for Mn and ∼54% for Zn. Maximum adsorption capacity was dependent on the type of ions. Adsorption of three metal ions on to zeolite followed by pseudo …

Functional expression of AtHMA4, a P1B‐type ATPase of the Zn/Co/Cd/Pb
We cloned and characterised a member of this family, AtHMA4, from Arabidopsis thaliana that clusters with the Zn/Co/Cd/Pb subclass of HMAs on phylogenetic analysis. Sequencing of the AtHMA4 cDNA showed that it contained the conserved motifs found in all P-type ATPases and also motifs that are characteristic of heavy-metal ATPases.
