HPLC method
- Details on study design: HPLC method:
- EQUIPMENT
- Instrument: High-performance liquid chromatograph LC-20AD (Shimadzu Corporation)
- Pump: LC-20AD (Shimadzu Corporation)
- UV-VIS detector: SPD-20A V (Shimadzu Corporation)
- Column oven: CT0-20AC (Shimadzu Corporation)
- Auto injector: SIL-20HT (Shimadzu Corporation)
- Systemcontroller: SCL-10 AVP (Shimadzu Corporation)
- Degasser: DGU-20 A3 (Shimadzu Corporation)
- Column: Inertsil CN-3 (150 mm x 2.1 mm I.D. particle size 5 µm, GL Sciences Inc.)
- Column temperature: 25°C
- Eluent: Methanol/purified water (60/40 v/v)
- Flowrate: 0.2 mL/min
- Measurement wavelength: 210 nm
- Sample size: 2µL
- Preparation of reference item solution: Each about 10 mg of methyl benzoate, linuron, naphthalene, fenthion, phenanthrene and DDT was weighed with an electronic analytical balance and dissolvedin methanol to prepare each of about 1000 mg/L solution. About 500 mg of formamide (for dead time) was weighed with the electronic analytical balance and dissolved in methanol to prepare about 50000 mg/L solution. These solutions were mixed and then diluted with the eluent ofHPLC analysis to prepare the reference item solution for the measurement of adsorption coefficient.
- Preparation of test item solution: About 100 mg of the test sample was weighed with an electronic analytical balance and dissolved in methanol to prepare about 1000 mg/L solution of the test item. Methanol was used as a solvent blank.
- Measurement of retention times for reference items, and making of regression line: The reference item solution was injected to the equipment and the retention times of the reference items were measured twice. The capacity factors (k) of the reference items were calculated.
Batch equilibrium or other method
- Computational methods:
- A regression line was made by the method of least squares using the known values of the adsorption coefficients and the logarithmic values of the capacity factors for the reference items.
