Five conical flasks
(250 ml) were supplemented with 5 g of five different raw materials (rice straw, molasses, wheat husk powder, potato peel powder, and milk straw) dissolved in 100 ml distilled water.
- ml bacterial suspension was inoculated into the conical flask
which contains 10 mL CASO liquid medium and 100 ml sterilized radioactive effluent of uranium tailings.
20 mL of 0.001 M AgN[O.sub.3] were added to 25 mL of 250 g/L WMRE in a 250 mL conical flask
and the pH of the reaction mixture was adjusted from 5.92 to 10 using 0.1 M NaOH solution.
The sample waste water was taken in four 250 ml conical flask
. The initial concentration of the COD of the textile waste water is kept same as initial concentration of the dye.
Bacterial degraded oil extract medium (1.0 g of the centrifuged) was measured into a 250 mL conical flask
. 10 mL of 0.5 M [K.sub.2] [Cr.sub.2] [O.sub.7] was added and gently stirred.
PG (3-7g) was taken in another conical flask
and 0.5g of carbopol-934 was added to it.
The fermentation medium containing Parkia biglobosa fruit pulp 250 g, N[H.sub.4]N[O.sub.3] 10.0 g, K[H.sub.2]P[O.sub.4] 4.0 g, MgS[O.sub.4] x 7[H.sub.2]O 1.0 g, and CaC[O.sub.3] 2.0 g was transferred to 1000 mL conical flask
and using a measuring cylinder, sterile distilled water was used to make up the volume to 1000 mL.
Extraction of crude enzyme during SSF was accomplished by adding 20 mL sterile distilled water into each conical flask
. The flasks were agitated overnight in a rotary shaker at 130 rpm in 25[degrees]C.
The optimum conditions: trace 1,2,4-trichlorobenzene was sterilized in the conical flask
in water, regulating solution for the corresponding pH value and temperature, and then it was put into the incubator, maintaining the full effect of illumination and oxygen pump sufficient oxygen, determination of degradation effect under different test conditions, every 6 days after determination of organic matter concentration, every time the 3 groups of repeat samples.
50 g of ground sample was taken into 500 mL conical flask
and 25 mL of water, 25 g diatomaceous earth and 150 mL chloro-form was added.
Two grammes of the extracted castor oil was weighed into a 200ml conical flask
already containing of 20ml acetic acid--chloroform solution (2 parts of acetic acid to 1 part of chloroform) and 1ml of saturated KI solution (4 parts of KI in 3 parts of distilled water) was added and allowed to stand in the dark for exactly one minute.
Oil extraction experiments were performed by using low frequency vibration experimental apparatus, conical flask
, sands, surfactant solution etc.
