Short electrospun fibres with average length of 50 700 μm were prepared by solvent assisted mechanical stirring and different amounts of short fibres were loaded into PTMC composites.
After magnetically stirring for 30 min, different amounts (0, 10, 50, or 100 mg) of P3HT were added into the mentioned solutions, and the color of the solution became dark red immediately.
After stirring for more than 1 h, different amounts of formaldehyde solution and resorcinol were added to each of the reaction solutions and stirred at 30 °C for 24 h, and subsequently heated at 100 °C for 24 h under a static condition in a Teflon-lined autoclave.
For the first investigation, the synthesis steps involve the mixing of a 50-mL (0.001 M) aqueous solution of HAuCl4.3H2O to different amounts of black cardamom extract under constant stirring of 250 rpm at room temp.
Open image in new window Fig. 2 Effect of different amounts of γ-Fe2O3 nanoparticles (MIONs) on the mercury separation (stirring time: 30 min, diluted petrochemical waste).
To study the effect of the mass of CNPs on adsorbent performance, 2.5 g of the DBT containing solutions, with an initial concentration of 1000 ppmw, was added to bottles containing different amounts of CNPs, from 0.1 to 8 g, and they were mixed well under stirring and left to equilibrate for 20 min.
NaOH solutions were prepared by adding different amounts of NaOH in 5 ml of methanol under vigorous magnetic stirring for 3 h.
Different amounts of NMBG powders (0, 0.2, 0.6 or 1 g) were added to the solution under stirring.
Then, different amounts of Na+MMT (1 5 wt%) nanoparticles were added to above mixture and stirring was continued for a further 6 h.
Second, different amounts of Hg2+or other metal ions were separately injected into series cuvettes containing the silver nanoparticles followed by vigorous stirring.
