Monitoring of degradation of 5 organic micropollutant under a multitude of scenarios

The spreadsheet contains HPLC integration peaks monitoring the photolytic and photocatalytic degradation of 5 organic micropollutants (ciprofloxacin, sulfamethoxazole, trimethoprim, venlafaxine and o-desmethyl-venlafaxine) under different conditions. The first sheets show the degradation by UV-A and UV-C photolysis and photocatalysis of each compound in individual solution in milliQ water (initial concentration of each, 2 mg/L). Later, all compounds are present in an initial mixture (concentration of each 2 mg/L, resulting in final mixture solution of 10 mg/L). The impact on degradation of adding 0.1 mM of peroxide in the solution for all 4 processes is studied. Additionally, the impact of: 1) of using simultaneous LED wavelengths (UV-A and UV-C combined); 2) using tap water as matrix; and 3) varying the initial pH for the 1st order kinetic rates of each compound in the mixture is investigated. Plots of the kinetic rate and calculations of EEO values (electrical energy per order consumption) are made. The last spreadsheets contain kinetic monitoring of several experiments performed by altering the composition of the matrix with the addition of nitrates, humic acids and bicarbonates. The data was used to obtain a surface-response box-behnken design of experiments.
