“…Several methods for the separation and preconcentration of molybdenum have been developed, enhancing the detectability and the versatility of the instrumental analytical techniques. The most widely used techniques for the separation and preconcentration of trace molybdenum include liquid-liquid extraction (LLE) [7][8][9][10][11][12][13], solid-phase extraction (SPE) [14][15][16][17][18][19][20] and co-precipitation [21][22][23][24]. Cloud point extraction (CPE), a new kind of LLE technique, has been receiving attention.…”
