EC number: 701-350-3
CAS number: -
of the Adsorption Coefficient (Koc) of the test substance on Soil using
High Performance Liquid Chromatography (HPLC) was determined in
accordance to OECD 121 and GLP. Sodium nitrate was used for measuring
the dead time of the substance and the reference substances used
includes; Acetanilide, atrazine, linuron, naphthalene, pyrazophos,
phenanthrene and DDT.
test satisfied the validity criteria:
The log koc derived from the same reference substances was not above
0.09 which was within the range of 0.5 log unit.
coefficient R2 of the linear regression equation was 0.9789 which met
within the requirement of above 0.95.
results show that the linear regression equation was: log Koc= 5.63 log
k' + 1.811, R2=0.9789, where k' is the capacity factor. The test
substance is a UVCB, under the condition of this test, a total of 13
constituents were detected. The log Koc values of the 1st-12th
constituent of the test substance were between 3.80 and 5.56, and the
log Koc of the 13th constituent was greater than 5.63.
The log Koc values of the 1st-12th constituent of the test substance
were between 3.80 and 5.56, and the log Koc of the 13th constituent was
greater than 5.63.
