Sorbents were separated from the samples by a nylon filter with the pore size of 0.45 µm (Carl Roth GmbH & Co. KG, Karlsruhe, Germany). All reactions were repeated at least three times, and the error never exceeded 5%. The LC/MS system consisting of a UHPLC chromatographic station ...
the discrete time domain as follows [15]: ig(k + 1) = 1 − Rg Ts Lg ig(k) + Ts Lg vVSI(k) − vg(k) (8) where vVSI is the inverter voltage vector, Rg is the combination of grid and line filter resistance, and Lg is the combination of grid and line filter inductance....

Samples for dissolved nitrate and nitrite, phosphate, silicate, and radium isotopes were taken at both groundwater stations. Radium samples were passed through a 1 µm cartridge filter followed by a MnO2-impregnated acrylic fiber (Mn-fiber) column to extract the dissolved radium [29]. The Mn...
The latter analyses are normally performed by passing the sample through a 0.45 µm filter before addition of a preservative. Smedley and Kinniburgh [42] reviewed the natural occurrence of arsenic in groundwater and the factors responsible for its mobilization. A key observation is that in most...
