For the repetitive centrifugal filtrations, α-synuclein in either granular or monomeric state was subjected to the filtrations at 14,000×g with a 2-min cycle for each filtration at 37°C using Microcon YM-30 and YM-10, respectively.
Moreover, the PTMM, which was dried at 25 °C in vacuum after each filtration cycle, could still maintain high hydrophilicity after 7 water filtration cycles and storing over 90 days.
During this mode, an elevated high instantaneous flux (60 L m−2 h−1) is initially applied for a short time (120 s), followed by a longer filtration (290 s) at lower flux (10.3 L m−2 h−1) and a backwash in each filtration cycle.
The permeate volume V at different filtration time t data were recorded at each TMP, fluxes were computed, and the flux-time plots were used to evaluate the fouling propensity of the feedwater (Amosa et al. 2016a, c).
Determination of uptake of radio-labeled substrate was conducted as follows: 700 µl of cells were collected in triplicates at each time point via filtration through a 25 mm GSVP 0.22 µm filter (Millipore) and filters were then rinsed 6 times with 2 ml aliquots of ASW.
HbA1c and creatinine were determined by standardized assays at each center and glomerular filtration rate (GFR) estimated using the Chronic Kidney Disease Epidemiology Collaboration formula (12, 13).
The optimum filtration and adsorption of pollutants were achieved at a filtration rate of 10 and 9 m3 m−2 h−1, respectively.
From the foregoing, since the flux-time plots are usually employed in predicting the flux condition at long filtration times, these results indicate that the permeate flux will approach a relatively steady-state at prolonged filtration periods.
However, ligands with bromide counter ions were dissolved in methanol following the same procedure, stopping at till filtration.
The intermediate model plot suggests that the mechanism started at a filtration time of 8 min and extended until 30 min.
