A novel bioadsorption composition suitable for removing heavy metal from waste water effluent, the composition comprising a biomass encapsulated sol-gel matrix. A process for preparing the biomass encapsulated sol-gel matrix is also provided. The bioadsorption composition may be suitably used to remove a substantial amount heavy metal (such as uranium) from a waste water effluent, particularly a dilute aqueous stream comprising a waste water effluent (such as mine water). Heavy metal may then be recovered from the bioadsorption composition, thereby rendering the latter as reusable.
