R.  aEvaluation of atrazine-chitosan sorption by diferential pulsed polarographic method.  c1999  aAtrazine (ATZ) is a broad-leaf, most applied herbicide to soils in the world. Atrazine is the leading member of a class of triazine ring-containing herbicides that includes simazine and terbuthylazine. One of the characteristics of the ATR is that it is found to be less biodegradable than other less substituted s-triazine ring compounds. In this work we investigate ghe sorption between ATZ and chitosan (CHI) by polarographic method.  achitosan  aAtrazina  aHerbicida  a(CHI)  aATR  aATZ1 aASSIS, O. B. G.1 aVIEIRA, D.
