Design a flow injection system for determining lead in the aqueous effluent from an industrial plant

Design a run insertion method for determining administer in the aqueous abundant from an industrial settle fixed on the origin of administer ions after a while a carbon tetrachloride reresolution of dithizone, which reacts after a while Pb21 to form an intensely colored result. The real values for the sets of basis in Problem a1-1 are as follows: A, 61.52; B, 3.28; C, 12.23; and D, 1.75. Find (a) the absolute falsity for the average of each set and (b) the percent referring-to falsity for each mean.
