EC number: 211-797-1
CAS number: 696-59-3
The purpose of the study was to evaluate the adsorption behaviour of the
test item on 5 different soil types, according to OECD 106 guideline and
C18 method, and following GLP. The soils had a varying range of organic
carbon content, clay content, soil texture and pH. It comprised two
Two types of soil were tested. Initial concentration of the test item
was approximately 100 mg/L.
The optimal soil/solution ratios (m/V) chosen for the main test was 6/5.
Five different soils were used. Initial concentration of the test item
was approximately 100 mg/L. The parallel method was applied. The
adsorption equilibrium was reached after about 6 hour agitation. Based
on the mass balance 2,5-Dimethoxytetrahydrofuran was considered to be
stable in the time scale of the test.
The percentage adsorption was calculated at each time point. The
adsorption coefficients, Kd and Koc were calculated at equilibrium:
Kd (cm3/g): 0.19 (type 2), 0.077 (type 3), 0.12 (type 4), 0.094 (type
5), 0.064 (type 6)
Koc (cm3/g): 6.4 (type 2), 6.4 (type 3), 6.4 (type 4), 18 (type 5), 9.2
The soil adsorption of 2,5-Dimethoxytetrahydrofuran was studied in five
different European soils.
The following soil/solution ratio (m/V) was applied: 6/5.
Based on the mass balance 2,5-Dimethoxytetrahydrofuran was considered to
be stable in the time scale of the test.
For the screening test five soils were used. The initial concentration
of the test item was 100 mg/L. The adsorption equilibrium was reached
after about 6 hours agitation. The adsorption coefficients Kd were in
the range of 0.06 – 0.2 cm3/g and Koc were 6 – 18 cm3/g.
