In this review, the research carried out to remove acetic ,acid, and the results are summarized with respect to the methods used and the effectiveness of the method.

Polyacrylamide for steel wastewater
Polyacrylamide for steel wastewater

It mainly includes three types of wastewater: oily and emulsion wastewater, acid-base wastewater, and chromium-containing wastewater. There are many types of pollutants in cold rolling wastewater, complex components, and large changes in water volume and composition, which bring great inconvenience to wastewater treatment.

The aim of this research was to determine the effect of formic ,acid, on pollutant decompo-sition in textile ,wastewater, subjected to treatment by the Fenton method. To estimate the effect of formic ,acid, on treatment efficiency for different types of textile ,wastewater, tested, COD reduction in mixtures of ,wastewater, and formic ,acid, was calculated.

Acetic ,acid, is one of organic ,pollutants, found in ,wastewater, produced from domestic households, industrial and agricultural practices, etc. However, HPLC with UV detection was not used for trace acetic ,acid, due to the limited sensitivity for its low wavelength (λmax = 205 nm) and weak absorption. The new generation Nexera X2 UHPLC system with a high sensitivity PDA detector SPD-M30A and ...

ABSTRACT: The effective removal of organic ,pollutants, in ,wastewater, is a key environmental challenge. In this work, an anionic covalent organic framework (named TpPa-SO 3 Na) was synthesized through a green two-in-one synthesis strategy with autocatalytic imine formation. The slowly generated acetic ,acid, …
