Claim 0:
1. A process for removing Co2+, Pb2+, Cd2+, Cr2+ toxins or mixtures thereof from bodily fluids comprising contacting said bodily fluid containing the toxins with an ion exchanger to remove the toxins from the fluid by ion exchange between said ion exchanger and said bodily fluid, the ion exchanger selected from zirconium metallate, titanium metallate, tin metallate, multinary metallate containing more than one of zirconium, titanium and tin, and mixtures thereof, the metallates respectively having an empirical formula on an anhydrous basis of:

AmZraTibSncMdSixOy 

where A is an exchangeable cation comprising potassium ion, sodium ion, rubidium ion, cesium ion, calcium ion, magnesium ion, hydronium ion or mixtures thereof, M is at least one framework metal selected from the group consisting of hafnium (4+) or niobium (5+), “m” is a mole ratio of A to total metal (total metal=Zr+Ti+Sn+M) and has a value from 0.10 to 15, “a” is a mole fraction of total metal that is Zr and has a value from zero to 1, “b” is a mole fraction of total metal that is Ti and has a value from zero to 1, “c” is a mole fraction of total metal that is Sn and has a value from zero to 1, where a+b+c >0, “d” is a mole fraction of total metal that is M and has a value from zero to less than 1, where a+b+c+d=1 and, “x” is a mole ratio of Si to total metal and has a value from 0 to 12, and “y” is a mole ratio of O to total metal and has a value from 2.1 to 33.
