Biosorption experimental were conducted using biomasses, named banana peels, pineapple leaves,mandarin-orange peels, ginkgo leaves and parachlorella. Those biomasses were　carbonized at an optimum temperatures and used as carbo-biosorbents for the removal of heavy metals and rare earth elements from aqueous solutions. The use of carbonized biosorbents in biosorption process is called “carbo-biosorption” in the present work. We find out a common properties and conclusions related the adsorbed ions and the carbo-biosorbents. We study the common properties that distinguish one category of ions from another and consequently, explain the affinity of one biosorbents with one group of ions than other. In addition some applicability approaches have been suggested in order to point out the viable and attractive aspect of the method.
