We also investigated the effects of reaction conditions such as temperature, pH, quantities of bark extract and AgNO3 concentration on the synthesis rate.
Batch biosorption experiments were performed to optimize the conditions of environmental parameters (pH, biosorbent quantity, heavy metal concentration and contact time).
Single-factor optimization was used to confirm the effects of temperature, pH, inoculum quantity, rotational speed, fermentation period, methanol content, and SVH concentration on CA production (Fig. 1).
To achieve the best fermentation results, the response surface methodology (RSM) was used to optimize key variables, such as temperature, pH, inoculum quantity, aeration condition, and fermentation period.
Fig. 1 Single-factor optimization of fermentation condition: a e effects of temperature, pH, inoculum quantity, rotational speed, fermentation period, and f the content of methanol and SVH on citric acid concentrations, respectively.
> > > Lithiasis formation depends on liquid intake, urinary pH, the quantity of crystals present in the urine and the persistence of crystalluria [ 58].
Kinetic studies showed that the rate of adsorption of copper is increased with increasing the solution pH and temperature, quantity of the zeolite and agitation speed.
The CCD was applied to design experiments for the evaluation of the interactive effects of the four most important operating variables namely temperature, NaCl quantity, pH and time.
The separation yield was 100 MBq (~99 %) of highly pure 149Tb in α-hydroxyisobutyric acid solution (pH 4.7), a quantity sufficient for preclinical application.
Herein, we used HEK 293T cells and ExtraPEG method (Rider et al., 2016) to investigate the influence of multiple storage conditions (temperature, cycles of freezing and thawing, pH) on the quantity changes and cellular uptake of exosomes.
