Question: consider a 100 step countercurrent distribution of solutes a amp...

Question details

Consider a 100 step countercurrent distribution of solutes A & B with distribution coefficients DA= 1 & DB = 0.6. Suppose the volumes of mobile and stationary are equal. If fractions 28-40 and 44-60 are each pooled find the % recovery and purity of each solute.

A. Tubes 44-60 have 90.2 % recovery of 88.5 % pure A Tubes 28- 44 have 97.4% recovery of 95.7% pure B

B. Tubes 44-60 have 92.2 % recovery of 93.4 % pure A Tubes 28- 44 have 77.4% recovery of 98.7% pure B

C. Tubes 44-60 have 96.2 % recovery of 87.5 % pure A Tubes 28- 44 have 92.4% recovery of 91.7% pure B

D. Tubes 44-60 have 86.2 % recovery of 90.5 % pure A Tubes 28- 44 have 67.4% recovery of 96.7% pure B
