What is breakthrough curve in adsorption?

A breakthrough curve in adsorption is the course of the effluent adsorptive concentration at the outlet of a fixed bed adsorber Breakthrough curves are important for adsorptive separation technologies and for the characterization of porous materials.

What are breakthrough time and breakthrough concentration in adsorption?

Breakthrough occurs when adsorbate reaches the end of the column and leaves with the column effluent. Breakthrough curves are plots of the adsorbate concentration in the column effluent as a function of time. In the breakthrough curves shown here, mass transfer is slower for Curve 1 than Curve 2.

What is breakthrough curve in chromatography?

A breakthrough curve is generated by graphing the amount of protein loaded versus the percent breakthrough. The DBC can be determined on the breakthrough curve at a loss of, for example, 10% protein (referred to as the QB10 value).

How is breakthrough concentration defined for adsorption in a packed vessel?

7) How is the breakthrough concentration defined for adsorption in a packed bed? a) It is the minimum detectable or maximum allowable concentration in the effluent from the bed.

How do you calculate a breakthrough curve?

Measuring breakthrough curves is a process that involves introducing a step change in gas composition, pressure, or flow rate. The process entails loading materials samples into a fixed bed and purging them with an auxiliary gas at an elevated temperature.

What is breakthrough analysis?

Breakthrough analysis is a powerful technique for determining the adsorption capacity of adsorbent materials under flow conditions. Breakthrough analysis allows users to more closely mimic process conditions than what can be achieved through static adsorption measurements.

What is breakthrough volume?

Breakthrough volume is defined as the minimum volume of carrier gas that will elute the analyte compounds from the adsorbent bed, as a function of temperature [24].

What is breakthrough curve ion exchange?

A breakthrough curve shows the solute or ion concentration in the effluent on the y – axis versus the effluent throughout volume on the x – axis. The area above the breakthrough curve represents the amount of solute or ions taken up by the columns.

What is a breakthrough analysis?

What does breakthrough mean in chemistry?

The term Breakthrough Volume is defined as the volume of Carrier Gas that will purge an analyte through one (1.0) gram of adsorbent resin in a desorption tube at a specific temperature.
