Most of these MCAs were detected in [P.sub.SLL] and [P.sub.SFB], whereas only 4 chloro-substituted alkanoic acids were detected in [P.sub.JCA] (i.e., chloroacetic acid, dichloroacetic acid
, 2,2-dichloropropanoic acid, and trichloroacetic acid).
Comparison of [H.sub.2][O.sub.2]/UV and Heterogeneous Photocatalytic Processes for the Degradation of Dichloroacetic Acid
The solvents used to dissolve PET are extremely dangerous and highly toxic and include: Phenol/tetrachlorethane, Phenol/Dichlorobenzene, Dichloroacetic Acid
, TrifloroaceticAcid and ortho-Chloropehnol.

Toxicological studies have shown that some HAAs (especially trichloroacetic acid and dichloroacetic acid
) and other DBPs can cause adverse effects, including cancer, in laboratory animals [7, 8].
Lee, "Characterization of photoreduced Pt/Ti[O.sub.2] and decomposition of dichloroacetic acid
over photoreduced Pt/Ti[O.sub.2] catalysts," Applied Surface Science, vol.
Solar photocatalysis has been implemented and evaluated in the pollutant treatment at pilot scale in heterogeneous reactors using Ti[O.sub.2]-P25, among which the following are highlighted: methylene blue , dichloroacetic acid
, chlorinated compounds mixtures, phenol , 4-chlorophenol , dyes , pesticides and herbicides [5-9], and emerging contaminants .
We attain electrical conductivities in excess of 50 S/cm when polyaniline films are exposed to dichloroacetic acid
. Subjecting commercially available poly(ethylene dioxythiophene) to the same treatment yields a conductivity as high as 250 S/cm.
HAA5 include monochloroacetic acid, dichloroacetic acid
, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid.
The label might refer to the negatively charged dichloroacetate anion related to dichloroacetic acid
or the acid itself.
