How Zeta Potential from Henry Equation works
Estimate zeta potential from electrophoretic mobility using Henry's equation ζ=3ημ/(2εf). Supply dynamic viscosity, absolute permittivity, and Henry function f(κa); the result depends on the electrokinetic regime. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Zeta Potential V
- The resulting zeta potential v returned as a number.
Limitations and assumptions
- Adsorption, wetting, and colloid models depend on surface preparation, temperature, pore structure, solution chemistry, and the chosen idealized isotherm or interaction model. Fitted parameters should not be extrapolated beyond their measurement range.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check units and significant figures, compare the result with limiting cases, and use measured or source-specific constants where available. Laboratory, safety, and regulatory decisions require validated methods and appropriate uncertainty analysis.
