“At pH 6.0, DCAA and TCAA yields decreased by 44.5% and 57.3%, respectively with the addition of 0.5 mg L(-1) iron , and decreased 39.5% and 49.4%, respectively with the addition of 0.5 mg L(-1) manganese.”
“The results … both iron and manganese can reduce the … dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) on chlorinating green alga Chlorella vulgaris (C. vulgaris) at a pH range of 6.0-9.… the decline of DCAA and TCAA was shown to be more significant at the low pH range.”
