Preservation of organics : part II : stability of chlorophenols in preserved natural water samples / by H.B. Lee, Y.D. Stokker, N. Arafat and A.S.Y. Chau.: En13-5/87-123E-PDF
"This study monitored the stability of 20 chlorophenols (CP) including the monochlorophenols in spiked water samples from five regions. Before the full-scale study was implemented, a pilot study was designed to evaluate the efficiency of three chemicals, namely, chloroform, copper sulfate and sulfuric acid, for the preservation of CP in water. Using Lake Ontario water as a typical sample, results indicated that both copper sulfate and sulfuric acid were effective preservatives. However, sulfuric acid was later chosen in the full-scale study since it was also used to preserve water samples for trace metal and acid herbicide analyses. The stability of CP in the spiked and sulfuric acid-preserved water samples was monitored by repetitive analysis of the samples immediately after spiking, as well as after 3, 6, 10, and 15 weeks of storage at 4°C in the dark. Under such conditions, the results in the full-scale study indicated no evidence of degradation for any CP in all samples over the 15-week study period"--Abstract, page ii.
