| Abstract | From this experimental investigation and literature review, Ultraviolet absorbance
At 260 nm (E260) with additional information such as TOC/E260, COD/E260,
E220/E260, apparent molecular weight distribution of E260 and hydrophobic E260 were
developed as surrogate parameters to evaluate water quality. These parameters are simple,
rapid, economical and practical for evaluating water quality. Possibilities are investigated
for the very first time to use hydrophobic E260 to identify synthetic organics in water and
wastewater.
The following conclusions hare been made:
(1) Natural water can be quickly characterized by using E260.
(2) Quick identification of hydrophobic organic components by using C-18 Sep- Pak
Cartridge is very promising. Hydrophobic E260 indicates the presence of
synthetic organics.
(3) The average removal efficiency of hydrophobic E260 by ozonation and
coagulation processes are 36% and 50%, respectively.
(4) BOD can be quickly estimated using TOC/E260, COD/E260 by relative equations. |
