Zeolites’ porous “cage” and its negative charge allows for the selective exchange of positively-charged toxins. Inside each zeolite are positively-charged exchangeable (lighter) metals known as cations, usually calcium, magnesium, sodium and potassium. These loosely held ions can be readily displaced by other substances, such as toxic heavy metals or other organics in a process called cationic exchange. Zeolites have a preference or affinity for heavy metals due to the positive charge and fit of heavy metals within the zeolite cage.
