Analysis of Headache Disease Data By Neural Networks.
2007
A process is disclosed for preparation of an amorphous polyaluminum sulfate composition of the formula Al(OH)x(SO4)y(H2PO4)z(H2O)w wherein x is about 0.75 to 1.5 y is about 0.7 to 1.07 z is about 0 to 0.2 w is about 2.0 to 4.2 with the proviso that the sum x+2y+z is 3. Water is withdrawn from a fairly fresh polyaluminum sulfate solution having the formula Al(OH)x'(SO4)y'(H2PO4)z'(H2O)w' wherein x' is about 0.75 to 1.5 y' is about 0.7 to 1.07 z' is about 0 to 0.
