For adsorbent concentration, 10 ml of 10ppm methyl orange, (for deltamethrin 100ppm) were taken in
conical flasks and 0.01, 0.02, 0.05, 0.1gm of CTAB-BT were added in each solution separately.
Ten
conical flasks (250 ml) contained 100 ml sabouraud broth media (Oxoid) at pH 6.5 were inoculated by different inocula (50, 100, 150, 200, 250, 300, 350, 400, 450, and 500 [micro]l) with A.
100 mL dilute hydrochloric acid (2mol/L) was slowly added to the
conical flask and to the beaker containing the filter paper, and stirred with a glass rod until no gas generated.
The broth was prepared by transferring 2.96 g of the Brain Heart Infusion (BHI) broth powder into a clean
conical flask and adding 76 mL of distilled water.
Sample [SG.sub.1] was prepared using a volume ratio of 1:1 by adding 50 mL of 0.001 M AgN[O.sub.3] solution to 50 mL of 250 g/L watermelon rind extract in a 250 mL
conical flask. The pH of the reaction mixture was 5.92 and was adjusted to pH 10 using 0.1 M NaOH solution.
Procedure: Plum fruit juice (1 ml) was taken in
conical flask and the volume was made to 10 ml by the diluting with 0.4% oxalic acid solution.
Each Cu source was weighed to contain 83.4 mg Cu/L in the 250 mL of the final solution and put into a 500-mL
conical flask. In step 1, sodium phosphate buffer solution (0.1 M, pH 6.0) and 0.2 M HCl solution were added in flasks containing samples of interest.
0.02g adsorbent was added to 50 mL of
conical flask containing 20 mL of CR solution containing 0.1 M NaCl solution.
The sample textile wastewater of known COD concentration was taken in ten 250 ml
conical flask. The prepared adsorbent were added to each
conical flask the dosage of 1,2,3,4,5,6,7,8,9,10 grams.
0.3 g of oil sample in a
conical flask and Wij's solution 3.8 mL was added into it.
The content of each
conical flask were kept in a shaker at 190 rpm and 30[degrees]C for 120 h.
For the preparation of hydro-alcoholic gels of cetirizine HCl, dilution solution (water) was taken in
conical flask. Then 0.2 g of cetirizine HCl was dissolved in 4.1-5.2g of distilled water and 1.3-1.7g PEG-1000 was added with continuous stirring using magnetic stirrer till completely dissolved.
