I think that researchers should stop inventing new modification methods of biosorbents, as there could be literally hundreds of them! The use of biosorbents should be cheap and environmentally friendly, but in many situations it is not achieved as multi step modification methods are used. Novelty? Here it is: 1) cost evaluation of the biosorption process; 2) fate of exhausted biosorbents; 3) development of full scale systems, where biosorbents are used as material; 4) recovery of adsorbed metals.
Agreed Pushpa Jha. However i do have the following things in mind which i want some expert to commemt on,ust changing the sorbent with same metal or using the sorbent (reported previously) for a different metal or a combination of these. The process is most often the same as that reported in prior art search, unless it involves biosorbent modification. How is 1 sorbent novel and the other one not considered as novel.

Bio-remediation and biosorption are two different processes. In Biosorption, the disposal of metal loaded biosorbent is in progress and has a lot of potential in this area.
