Fikk 's Law deskripsikan bahwa ia difusion particles of f vour regions of high concentration to konsentration. Ini adalah fundatal in undertal mengerti how vouruns move dusting adpretion and stripping ing in chemiciering. Applying lavourevoule.

Fikk 's Law Fundamentals

Jadi, kita akan melakukan proses yang sama dengan apa yang kita lakukan.

1f 1f; FLT: 0 123; Ji = -D (dC / dx) 1f FLT: 1 13.1f;

Dimana ia berada, ia akan menjadi FLT 0; 0; 3; J 1; 1; FLT: 1: 1; 13; ia adalah flux, yaitu the diffusion fLT: 2; D 11; FLT: 3; 33x; 33333333333333333333333333333333333333333333T;

Application is Absorption and Stripping

Ini penyerapan, sebuah gas or liquid phase menyerap solute froem another phase. Stripping involves removat a component frofum a mixture. Both morses rry on diffusion distion by concentratious dice, which cun be modeled using fass 's law.

Calculating concentration profiles involvos the diffusion equation derived fromm Fick 's Law, often weh boundary conditions specic to the system. (Ini provides insighan intho how concentratioon varieos across thae medium.)

Calculating Concentration Profiles

Ini adalah satu-satunya cara untuk melakukan hal-hal yang lebih baik.

11; Syaria1; FLT: 0 AF3; Abo3; Abo3; = D refakut C / Axx ² SUR1; FLT: 1; ASA3;

For steadid- state conditions, the equation simple fies to:

111; FLT: 0 Aver3; 0 = D NUT² C / NUX ² S01; FLT: 1: 1; ASA3;

Solutions to thesee equations, with avacioate e boundary conditions, yield the concentration profiles across te inservoon or stripping medium.

  • Define boundary conditions
  • Menentukan difusion coexiticient
  • Solve the diferensiasi equations
  • Analyze the resalting concentration profile
