Total concentration and fractions of aluminum in water samples collected from the Le An River were determined by PCV complex colorimetry. Taking advantage of developed empirical models combined with nonlinear multivariate statistical technique, concentration of aluminum adsorbed by suspended particles, i.e. [Alads] was regressed with concentration of monomeric aluminum,i.e.[Almono], pH and turbidity. However, aluminum strongly bound with humic substances, i.e.[Alorg] was universally too low to detected in this experiment, and at least, it may be partially related with much lower DOC level along the Le An River.
