“…This is a significant trapping way to identify the functional groups present in the samples. The absorption peaks at 3422 cm -1 ~3387 cm -1 can be consigned to the stretching vibration of hydroxyl (-OH) groups and presence of H2O due to the fact that iron oxide form retains certain adsorbed water (Sangaiya &Jayaprakash 2020, Tadic et al 2014). In addition, 2362 cm -1 spectrum in CK, 2372 cm -1 spectrum in LB, 2365 cm -1 spectrum in oilfield produced water, 2363 cm -1 spectrum in oilfield produced water with bacteria belongs to atmospheric presence of CO2 (Sangaiya &Jayaprakash 2020).…”

The corrosion behavior of Q235B carbon steel is investigated in water, LB medium and oilfield produced water adding Pseudomonas fluorescens FSYZ01. After immersion for 13-days, weight loss of carbon steel with this strain decreased by 32.23%, 54.07%, and 78.34% respectively. XRD results show Pseudomonas fluorescens FSYZ01 inhibited conversion of iron oxides by hindering oxygen from approaching metal surface.FT-IR and XPS results show that specific functional groups and bonds reacted with Fe(II/III) to form a dense and stable chelate-oxide protective layer, thereby inhibiting corrosion. Py-GCMS results demonstrate the bacteria degraded C12 to C20 alkanes in oil.The inhibitory mechanism of crude oil degrading bacteria Pseudomonas fluorescens FSYZ01 on the carbon steel corrosion was proposed, so as to slowing corrosion of oilfield produced water system pipeline and prolonging its service life, helping to comprehend the microbial corrosion in the actual environment.

“…This result clearly indicates that wt% of Co dopant alters the phase of barium ferrite nanoparticles as well as it is assured that optimum level of Co is needed to act as dopant. The average crystalline size is calculated as 32 nm of sample (a1) by using Debye-Scherrer's formula [19].…”

The M doped BaFe2O4 (M- Co, Ni and Mn) nanoparticles were synthesized through auto combustion method by using n-heptane as a surfactant. And also the weight percentage (wt%) of metals such as cobalt, nickel and manganese (10 wt%, 8 wt% and 6 wt%) in BaFe2O4 was optimized. The prominent orientation (212) and (311) of M doped BaFe2O4 is confirmed from XRD especially in 10 wt% of respective metals. The addition of metal doped in barium ferrite specific vibration on 770 and 445 cm− 1 in FTIR spectra indicated the formation of M doped BaFe2O4. The influence of n-heptane as a surfactant on morphological change occurred in different metal doped was visualized from FESEM and TEM images. The different morphologies such as spherical, hexagonal platelets and small rectangular bar shaped were observed only by the inclusion of barium ferrite at surfactant medium. The analysis of EDX spectrum reflected the atomic percentage of elemental presence in the samples of M doped barium ferrite. Magnetic properties of these samples were studied by VSM. It revealed that 28.41 emu/g saturation magnetization (Ms) with 1655.64 Oe coercivity (Hc) and also induced ferromagnetic behaviour. The variation of dielectric constant indicated from dielectric study.
