Chapter 2, Problem 2.50P
Interpretation Introduction

(a)

Interpretation:

The plot that would yield a straight line and helps in determining the parameters a and b should be determined.

Concept introduction:

A hazardous waste needed to be disposed. So, the solution of this waste is pumped into a storage tank. Then, the solution subjected to chemical treatment. Due to the chemical treatment, the concentration (C) of the decomposing waste has been reported to vary with time (t) according to the formula.

C=1/(a+bt)

Where a and b are constants.

Interpretation Introduction

(b)

Interpretation:

The value of a and b should be estimated using graphics software. The graph of C vs t to show both measured and predicted values should be plotted.

Concept introduction:

A hazardous waste needed to be disposed. So the solution of this waste is pumped into a storage tank. Then, the solution subjected to chemical treatment. Due to the chemical treatment, the concentration (C) of the decomposing waste has been reported to vary with time (t) according to the formula.

C=1/(a+bt)

Where a and b are constants.

Interpretation Introduction

(c)

Interpretation:

Using answers in part (b), the initial concentration of the waste in the tank and the time required for C to reach its discharge level should be calculated.

Interpretation Introduction

(d)

Interpretation:

The little confidence in the time estimated in part (c) should be explained.

Do question 9 please! Question 7 Is just there for reference!!
7) You are tasked with separating two proteins by ion exchange chromatography on a 30 cm long column with an inner diameter of 2 cm. The resin has a diameter of 100 μm and a void fraction of 0.3, and your mobile phase flows through the column at a rate of Q = 5 cm³/min. The Van Deemter coefficients A, B, and C have been determined to be 0.0228 cm, 0.0036 cm²/min, and 0.00053 min, respectively, for both proteins. Protein A elutes from the column with an average retention time of 27 min and standard deviation of 0.8 min. Protein B elutes from the column. with an average retention time of 33.8 min and standard deviation of 1.0. a) How many theoretical plates does the column contain? b) What flow rate (Q) will give you the maximum resolution? c) What is the minimum height of a theoretical plate for the system?
