“…Literature survey revealed many methods with different analytical techniques for individual or simultaneous determination of PCT in different sample types. The technique includes voltammetry [9][10][11][12][13][14] , CE [15][16] , TLC [17][18] , HPLC [19][20][21] , RP-HPLC [22][23] , LC-MS 24 , LC-MS-MS [25][26][27][28] , GC 29 , FTIR 30 , spectrofluorimetry [31][32][33][34] , kinetic spectrophotometry [35][36] , derivative spectrophotometry [37][38] , indirect spectrophotometry 39 , direct spectrophotometry [40][41][42][43][44][45] etc. The techniques other than spectrophotometry require lengthy procedures, highly sophisticated analytical instruments and some amount of the organic solvents contributing towards high cost of the analysis.…”
