proportional correlation with transformation byproducts (i.e., correspond to one-electron transfer reaction, Scheme 1). On the other hand, glyphosate and dissolved Mn in the effluents show 1:0.75 ratio which is respond to a chelation mechanism. In the presence of BSA association the extent of dissolution on Mn oxides diminishes and the glyphosate to dissolved Mn ratio is 1:0.55.
