The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Soil anaerobic leaching method:
During lixiviate, at first to sample cell 1 together with the rubber cap 9 (m that weighs
1); Next extracts the hole plug 3 that sample cell 1 front end is provided with, and soil sample is pushed sample cell 1, and soil sample is pressed the piston of sample cell 1 in the sample introduction process, behind the sample introduction beyond the Great Wall hole plug 3 cover rubber simultaneously and emit the 9 (m that weigh
2), (m of poor quality that weighs for twice
2-m
1) be soil quality (m); Connect liquid injection pipe 6 that injects leaching liquor and the air injection pipe 5 that feeds gas by threeway 7 at last, rotation diplopore cock 8 earlier, sample cell 1 is communicated with liquid injection pipe 6, advance the piston of liquid injection pipe 6 that leaching liquor is injected, leaching liquor can be chosen arbitrarily according to measuring needs, and the addition of leaching liquor satisfies the test demand according to measuring needs simultaneously; Rotate diplopore cock 8 then sample cell 1 is communicated with air injection pipe 5, advance the piston of air injection pipe 5 that gas is injected, gas can be N
2, CO
2Or inert gas.
Vibration, the diplopore cock 8 of swivel tee 7 make sample cell 1, air injection pipe 5 and liquid injection pipe 6 not connected, take off sample cell 1 and cover rubber cap 9 and vibrate.
Filter, taking off rubber cap 9 links to each other sample cell 1 straight up with syringe-type membrane filter 10, promoting piston together discharges the portion gas in the sample cell 1 together with the air in the syringe-type membrane filter 10, oxidized when filtering to prevent leaching liquor, then with syringe-type membrane filter 10, wherein, syringe-type membrane filter 10 is built-in 0.22 micron filter membrane, by conduit 11 and collector tube 12 with link to each other, the piston that promotes sample cell 1 filters, filtrate enters collector tube 12 immediately, and sample is sample after the anaerobism lixiviate in the sample cell 1.
