Comparison of non-protected fluid room temperature phosphorescence properties of α-naphthyloxyacetic acid and β-naphthyloxyacetic acid

Simultaneous Determination of Plant Growth Regulators 1‐Naphthylacetic Acid and 2‐Naphthoxyacetic Acid in Fruit and Vegetable Samples by Room Temperature Phosphorescence

“…Thus, NAA has been determined by room‐temperature phosphorescence (RTP) in the presence of β‐cyclodextrin or a micellar agent (Muñoz de la Peña et al , ; Segura Carretero et al , ; Murillo Pulgarín et al , ). NOA has also been determined with phosphorescence methods over the past few years; some such methods use heavy‐atom induced room temperature phosphorescence (HAI‐RTP; Li et al , ), a micellar agent (MS‐RTP; Segura Carretero et al , ) or a cyclodextrin (CD‐RTP; Muñoz de la Peña and Duran Meras, ).…”

“…Thus, NAA has been determined by room-temperature phosphorescence (RTP) in the presence of b-cyclodextrin or a micellar agent (Muñoz de la Segura Carretero et al, 1998;Murillo Pulgarín et al, 2003). NOA has also been determined with phosphorescence methods over the past few years; some such methods use heavy-atom induced room temperature phosphorescence (HAI-RTP; Li et al, 2000), a micellar agent (MS-RTP;Segura Carretero et al, 1996) or a cyclodextrin (CD-RTP; Muñoz de la Peña and Duran Meras, 1993). This paper reports the simultaneous determination of 1-naphthylacetic acid (NAA) and 2-naphthoxyacetic acid (NOA) by micelle-stabilised room temperature phosphorescence (MS-RTP) in agricultural products such as tomato and fruits (apple, strawberry, orange and plum), using a simple spectrofluorometer.…”
