Add all ingredients, except "Kelzan," to an appropriate grinding mill (e.g., Attritor, ball mill, etc.). Mill until the atrazine particles attain an average particle size of less than 5 \mm. Add the "Kelzan" and mill for 15 min or until completely dissolved. (Predetermine the amount of triethanolamine required to bring a mixture of all ingredients to pH 7.0.)
