“…The CCD matrix is comprised of three parts: factorial matrix (assays 5, 6, 12, 13), a star matrix (assays 1,3,8,11) and a group of points at the center of the experiments (assays 2, 4, 7, 9, 10).…”

“…In the USA, pond water contained 0.09 -1.7 mg of amino methyl phosphonic acid (AMPA) has been detected [5]. Several countries, including the United States, Canada, and Brazil have recorded some negative effects on human and animal health due to the glyphosate contamination in water [6][7][8][9][10]. Some studies reported that herbicides are entering the aquatic system, although in extreme low concentrations may introduce a potential hazard for human, in particular where no advanced water treatments facility are used [11].…”

The presence of herbicide is a concern for both human and ecological health. Glyphosate is occasionally detected as water contaminants in agriculture areas where the herbicide is used extensively. The removal of glyphosate in synthetic solution using advanced oxidation process is a possible approach for remediation of contaminated waters. The ability of electrochemical oxidation for the degradation and mineralization of glyphosate herbicide was investigated using Ti/PbO2 anode. The current intensity, treatment time, initial concentration and pH of solution are the influent parameters on the degradation efficiency. An experimental design methodology was applied to determine the optimal condition (in terms of cost/effectiveness) based on response surface methodology. Glyphosate concentration (C0 = 16.9 mgwhen the optimal conditions were imposed (current intensity of 4.77A and treatment time of 173 min). The removal efficiencies of glyphosate and total organic carbon were 95 ±16 % and 90.31 %, respectively. This work demonstrates that electrochemical oxidation is a promising process for degradation and mineralization of glyphosate.

“…In our previous work [4], NF was shown to be a feasible method to recover glyphosate from its production liquor in the glycine-dimethylphosphit process. Luo et al [5] used NF for desalination and recovery of iminodiacetic acid (IDA), which is an important intermediate for glyphosate.…”
