Neochloris minuta and Neochloris alveolaris grown in nitrogen-rich (+ N) and nitrogen-depleted (-N) media were tested for their heavy metal maximum biosorption capacities (q_max) and adsorption percent efficiencies (R%). By removing nitrogen from the growth media, both algal species showed an increase in their lipid content and a decrease in their protein content. Langmuir and Freundlich adsorption isotherms were used to determine the q_max and adsorption efficiencies of the + N and −N algae in the recovery of Pb²⁺, Cd²⁺, Zn²⁺, Cu²⁺, and Ni²⁺. When comparing the …
