Additional information

AlASP is a very sparingly soluble amorphous phosphate.Accurate measurement ofthe water solubility of AlASP, therefore, requires a procedure which minimizes the measurement error. One method of assuring accurate measurement is use of large volumes of water and precise solute detection and analytical procedures.

AlASP spontaneously forms a finely dispersed gelatinous suspended solid in water which is very difficult to filter out. Therefore, it is possible that part of the Al detected is not, in fact, dissolved but suspended. Therefore the value of0.0213g/lis a "worst case" scenario.
