| Propazine (2-chloro-4,6-bis(isopropylamino)-s-triazine) is an herbicide used to control annual grasses and broadleaf weeds in the production of sweet sorghum, carrots, celery, and fennel.1 The herbicide provides post-emergent protection by interfering with photosynthetic electron transport. Propazine is highly persistent in the environment with half-lives ranging from 35 to 231 days. The goal of our group is to develop an electro-analytical technique to quantify propazine in the low to sub-parts per billion (ppb) range using a hanging mercury drop electrode (HMDE) and differential pulse voltammetry (DPV). Our developed procedures are based upon our group's earlier work on the herbicide atrazine. This project involves the standard additions method, error analysis, and detection limit calculations. Such a method may be useful for industries interested in water quality measurements. 1. See http://extoxnet.orst.edu (accessed 11/1/06) |
