Abstract
A natural reddish dye from the red rose petals extracted with 0.5 M sulfuric acid solution was applied to chemiluminescent enhancement of active oxygen produced by neutralization energy of acid-base reaction. Using a flow injection system equipped with the enhancement technique, sulfuric acid of high concentration was rapidly, easily and sensitively determined. The 3 lines are consisted of sodium hydroxide (6 M), octadecyltrimethylammonium chloride (1×10-2 M) and the reddish dye at a flow rate of 3.5 ml/min each. Analytical characteristics of the proposed system are as follows. Magnitude for the determination: 818 M in the 10 μl injection method (S/N=1.5), analytical time required: ca. 10 s, relative standard deviation: 2.0% for 5 repeated runs of the 9 M sulfuric acid solution. The determined values for the proposed system agreed well with those for the conventional method.
