| Cyanazine (2-[[4-chloro-6-ethylamino)-s-triazin-2-yl]amino]-2-methylpropionitrile) is a triazine herbicide used to control annual grasses and broadleaf weeds. The herbicide provides post-emergent protection by interfering with photosynthetic electron transport. Suitable crops can either degrade or safely metabolize the herbicide. The most common use of cyanazine is in corn production. Other uses include cotton, sorghum grain, and wheat fallow.(1) The goal of our group is to develop an electro-analytical technique to quantify cyanazine 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 work involves the standard additions method, calibration sensitivity, 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 10/14/05).
