Al-Qahtani [23], has investigated the wastes of some fruits, such as kiwi and tangerine peel, to remove toxic cadmium and other heavy elements, chromium and zinc ions in aqueous solution.
The bioadsorption capacity of fruit wastes from banana peel, lemon and orange peel was evaluated by Kelly-Vargas et al. [24] in some heavy metals.
As reported by Mohapatra et al. [34], banana peel is found as a good source of pectin (10-21%), lignin (6-12%), cellulose (7.6-9.6%), hemicelluloses (6.4-9, 4%) and galactouroninc acid.

This process was tested by Kuncoro et al. [13] for Hg(II) recovery at pH 5-6.
Ahmed et al. [16] deposited chitosan on a synthetic polymer (bringing mechanical properties) before immobilizing nickel.
Cha et al. [18] describe an example of use of chitosan for the controlled delivery of cis-platin.
Chitosan has been used by Wu et al. for the encapsulation of gold nanoparticles for immunoassay procedures.
