Novel materials and processes have been developed that can be used to remove arsenic from drinking water and semiconductor manufacturing waste and can also remove phosphate from aquaria with high efficiency.  These materials are metal organic coordination polymers that have startlingly high capacities for arsenic and phosphate that exceed 15% by weight.  The sorption of the target ions is effective over a wide range of pH and varied water chemistry. Phosphate removal from aquarium waters exceeds that of commercial products for the same purpose and is effective even in saltwater tanks. These materials are also amenable to developing processes for a one-step treatment of aqueous waste streams from gallium arsenide production. Removal of arsenic from juice and rice syrup is also possible.<br/>
