Hi @LatinXChem, presenting my work ‘Evaluación de la actividad de las algas pardas para la remoción de metales pesados en aguas contaminadas con efluentes residuales domésticos' at #LatinXChem24 #LatinXChemEnv #Env069

@WaldmanLab @LatinXChem Basically, the metals remain contained on its interior, but they can be recovered through an acidic "elution" (as it is done with some membranes/raisins), which attatches protons to the -OH and -COOH groups of the alginate, and thus, disables metal sorption.

@TheChemMixt @LatinXChem Gabriel, congratulations on your work! Can you tell me what happens with the algae after the removal? If they are still in the environment, the metals are not going anywhere, are they?

@WaldmanLab @LatinXChem This is why is has been found the Sargassum to be rich on metals such as Ni, Cr and As. Fortunately, they can be removed with an acidic treatment (pH < 3), which shifts the equilibrium to the formation of alginic acid, a condition that is not naturally met.

@WaldmanLab @LatinXChem Now, thanks to the "egg box" structure that the alginate obtains after the intraction with the metals, they are kept strongly binded, and thus, remain inside it, as you say. They act like a "metal disposal container"

@WaldmanLab @LatinXChem First of all, I really appreciate your comments on the work!
