After
the experiment, the corrosion products on the metal surface were removed
by pickling solution (deionized water, HCl, and hexamethylenetetramine).
An electronic balance (METTLER TOLEDO MS105) was used to weigh the
mass of coupons. The corrosion rate of metal was calculated according
to eq 8. where V is corrosion rate
(mm a^–1), m is the weight difference
before and after corrosion (g), s is the area of
coupons immersed in solution (cm²), t is
the corrosion time (h), and d is the metal density
(g cm^–3).
A viscometer (Brookfield) was used
to measure the viscosity of the system at different time nodes.

Solubility of Bromine Flame Retardants

Solubility, expressed as saturated concentration (cs, in mM), is the maximum concentration of a solute that can be dissolved in a solvent. cs of individual pure BFR in ScCO2 was measured gravimetrically using an analytical balance (MS105, Mettler-Toledo, USA) with a readability of 0.01 mg and calculated with the following equation: Since mass removal of BFR is not gravimetrically measurable in polymer samples, the Br content of polymer samples (CBr/polymer, in wt.%) before and after extraction were determined using an X-ray fluorescence analyzer (XRF) (Vanta C, Olympus, Japan) applying RoHS plus method. For this determination, the powdered polymer samples (200 mg) were pressed into a circular shaped disc using a hydraulic crimper (MSK-510M, MTI Co., China) at 160 °C and 5 MPa for 5 min. The mass removal of BFR in polymer matrix was calculated using the formula ∆(CBr/polymer•m)/CBr/BFR, where CBr/BFR is Br content in BFR compound (wt.%), only then the solubility can be calculated with Eq. (1) .All experimental data were displayed in a format of mean value ± standard deviation.

PM2.5 Collection and Suspension Preparation

Check if the same lab product or an alternative is used in the 5 most similar protocols

PM_2.5 was collected outdoors from November 2019 to February 2020. The average temperature and humidity during the sampling period are shown in Table 1. PM_2.5 sampler (Dandong Better Instruments Co., Heilongjiang, China) was set at the Chinese Research Academy of Environmental Sciences, Beijing. The sampling flow rate was 16.67 L/min. PM_2.5 was collected with Teflon membrane. Teflon membrane equilibrate in a constant temperature and humidity (20~25 °C, 50% humidity) box prior to this collection for 24 h, weigh the membrane with a 0.01 mg electronic scale (MS105 Mettler Toledo, Zurich, Switzerland) prior to sampling, weigh again after sampling, and record the difference in membrane weights. The collecting sampled membranes were stored at −20 °C until analysis. Each membrane is collected for 23 h (4:00 p.m. to 3:00 a.m. the next day).
The following is the process of PM_2.5 suspension preparation. The Teflon membranes loaded with PM_2.5 were ultrasonically extracted with ultrapure water. The mixture was then freeze-dried, and the solids were accurately weighed using a one ten-thousandth balance. Finally, the solids were mixed with DMEM medium without serum to form PM_2.5 suspension. PM_2.5 suspension was stored at 4 °C and protected from light before use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
