Provided is a granular filtration media comprising a mixture of granular filtration media and less than 5% of nanofibers based on the dry weight, method of making the same and uses of the same for removing contaminants from water, including metals, heavy metals, synthetic or natural organic matters, colloidal or suspended particles to improve the chemical safety and purity of water for the purpose of water purification, specifically, one embodiment of the present invention disclosed is use of the granular filtration media to remove particulate lead from high pH water.

Granular filtration media mixture and uses in water purification

Disclosed is a method for selectively binding and separating phosphate anions from a liquid medium by providing a cross-linked molecularly imprinted polymer including cross-linked chitosan having selective binding affinity for phosphate ions, phosphate containing molecules, or a combination of both.

Method for selectively binding and separating phosphate anions

Disclosed is a cross-linked molecularly imprinted polymer including cross-linked chitosan having selective binding sites for phosphate ions, phosphate containing molecules, or a combination of both.

Molecularly imprinted polymers

A molecularly imprinted polymer sensor device for detecting the presence of a taggant molecular structure in a fluid is disclosed. The molecularly imprinted polymer sensor device comprises a molecularly imprinted crosslinked polymer having a crosslinked core and a plurality of polymer arms attached to the core, wherein the core has molecular sized cavities adapted to selectively receive and bind displacement molecules having the taggant molecular structure and a colorimetric indicator, said displacement molecule being selectively removed from the molecularly imprinted crosslinked polymer and replaced with the taggant molecular structure upon exposure to the fluid containing the taggant molecular structure therein, thereby indicating the presence of the taggant molecular structure in the fluid.
