Precipitation Gravimetry

16.1K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Area of Science:

  • Environmental Science
  • Acoustic Oceanography
  • Sedimentology

Background:

  • Acoustic backscatter is crucial for estimating suspended sediment concentration and particle size.
  • Heterogeneous suspensions pose challenges due to nonlinear sonar equation inversion and noise sensitivity.

Purpose of the Study:

  • To develop a robust method for inverting acoustic backscatter data from multi-frequency, multi-class sediment suspensions.
  • To improve the accuracy and stability of suspended sediment concentration and particle size estimations.

Main Methods:

  • Reformulated the sonar equation for multi-frequency, multi-class suspensions into a matrix form.
  • Derived an integral expression for direct inversion of sediment concentration.
  • Applied a nonnegative least squares solver for recovering sediment class concentrations and sizes.
  • Utilized spectral analysis to differentiate concentration fluctuations from noise, enabling temporal filtering.

Main Results:

  • Accurate recovery of single- and dual-class concentration profiles was demonstrated through laboratory validation.
  • The method successfully estimated sediment sizes when the number of frequencies exceeded the number of classes.
  • Temporal filtering significantly improved inversion stability and interpretability.

Conclusions:

  • The proposed matrix-based sonar equation inversion provides a practical framework for studying suspended sediment dynamics.
  • This approach is applicable to fluvial, estuarine, and coastal environments, aiding in understanding cohesive-noncohesive sediment interactions.
