摘要：In this paper, the principle of a new absorbance ratio-derivative method was described. The experimental methods of derivation with subtraction technique on ordinary spectrophotometer and simultaneous determination of phenol and resorcin were studied. The result is satisfying. The recovery of resorcin and phenol is in the range of 99.4%-104. 2% ( n = 25, RST = 1. 1%)and 97.1%-102.8% (n = 25, RSD=1.6%) respectively.
