Dissolved phosphorus levels in fresh municipal wastewater.

The influence of wastewater lag-time to the concentrations of dissolved phosphorus was investigated. The dissolved phosphorus levels of fresh municipal wastewater and the rate at which phosphorus dissolves in untreated municipal water was studied. Dissolved phosphorus initially accounted for 34% of total phosphorus in the used water.

Identification of hydrolysis products of AlCl(3)*6H(2)O in the presence of sulfate by electrospray ionization time-of-flight mass spectrometry and computational methods.

ElectroSpray Ionization-Mass Spectrometry (ESI-MS) and computational methods (DFT, MP2, and COSMO) were used to investigate the hydrolysis products of aluminium chloride as a function of sulfate concentration at pH 3.7. With the aid of computational chemistry, structural information was deduced from the chemical compositions observed with ESI-MS.
