Abstract
A process for delivering and/or removing metal from a biological system by loading a titanate sorbent with a biometal either before introduction into the system for delivery to a site within the system or after introduction into the system for delivery to a site where there is an excess accumulation of metal and thereafter the sorbent is loaded at the site with the excess metal and is removed from the system.
Claims8
A method for delivering selected metals or metal compounds having therapeutic treatment properties to a selected site in the biological systems of human and animal patients comprising the steps of:
- a) selecting a biometal from the group consisting of metals and metal compounds known to have a beneficial effect for a patient when delivered to the selected site;
- (b) loading a titanate sorbent with said biometal;
- and
- (c) delivering the loaded sorbent to the selected site within said biological system whereby a portion of said loaded sorbent is absorbed at the site;
- and,
- (d) removing excess loaded sorbent from said system.
A method for delivery of metals or metal compounds having therapeutic treatment properties to selected sites in a biological system of a human or animal patient where a health problem exists that is expected to beneficially respond to the deliver of said metals, said method comprising the steps of:
- a) loading a selected therapeutic metal or metal compound onto a titanate sorbent selected from the group consisting of MST having a general chemical formula of HNA Ti2O5xH2O where x˜2-4 and APT having a general chemical formula of HvNawTisO5(xH2O)[yHzO2] where v+w=2 and z=O to 2;
- b) delivering the titanate sorbent to the selected site of a patient whereby the metal that accumulates at the site provides a therapeutic treatment;
- and
- c) removing the loaded sorbent from the system.
