The present invention relates to a sorbent which is suitable for binding metals from solutions, the production of a corresponding sorbent as well as the use of the sorbent for binding metals from solutions.

The present invention provides for a water retention polymer capable of retaining water for long durations and in huge amounts and the method of preparing the same. The polymer is capable of releasing the retained water slowly and as per the requirements of the crop and soil. Thus, the water retention polymer minimizes the water requirement during irrigation and other purposes. Further, the said polymer is eco-friendly, pollution free and completely biodegradable. The polymer can be used to grow plants on barren lands and marble slurry. The use of this polymer also minimizes the requirement of fertilizer for the crops. Further, the said water retention polymer is low-priced and hence affordable by farmers. The reduction in water requirement and fertilizer due to the use of this water retention polymer reduces 60% overall production cost for the farmers and hence results in more income generation from agriculture.
