JAOAC Int. 84, 993-999 (2001): Review of advances in the application of TLC and HPTLC for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds for the period 1998-2000. Analyses are covered for a variety of samples, such as food, biological, and environmental, and for the residues of pesticides of various types, including insecticides, herbicides, and fungicides, belonging to different chemical classes. References of formulation analysis, hydrophobicity studies, and the use of TLC and thin-layer radiochromatography (TLRC) for the studies of pesticide metabolism, degradation, uptake, and related studies are also included. Topics covered are Materials and Techniques (sample preparation; thin-layer plates, mobile phase selection and plate development; detection and identification of zones; quantitative determination), Applications of TLC (OC and pyrethroid insecticides, OP pesticides, herbicides and plant growth regulators, fungicides, multiclass and miscellaneous pesticide determinations, theoretical, degradation, metabolism, uptake, hydrophobicity, and soil mobility studies, multidimensional methods); 64 references.

Acta Chrom. 9, 123-132 (1999). TLC of phenolic pesticide residues (m-nitrophenol, p-nitrophenol and p-aminophenol) in banana fruits and plant-tissues on stannic arsenate–silica gel layers. Several mobile phases of different polarity were evaluated; separation of m-nitrophenol, p-nitrophenol, picric acid and p-aminophenol was best achieved with ethanol – 1.0 M citric acid 1:3. Visualization by spraying with AgNO3 – reagent (saturated AgNO3 solution in acetone 1:20 diluted with water until the precipitate of AgNO3 was dissolved) followed by heating at 105 °C, or by spraying with a mixture of 15 % FeCl3 and 1 % K4Fe(CN)6 1:1.

J. Planar Chromatogr. 29, 391-393 (2016). HPTLC of endosulfan from visceral tissue on silica gel with (1) hexane – acetone 4:1, (2) hexane – acetone 9:1, (3) acetone – benzene 4:1, (4) cyclohexane – chloroform 3:2 and (5) benzene – methanol 2:3. Detection by spraying with 5 % sodium hydroxide and then 2 % pyridine. The plate laid for 5 min and then was sprayed with p-aminoazobenzene reagent (0.25 % p-aminoazobenzene in ethanol, 25 %). The hRf values of endosulfan in the selected systems were 97 for (1) and (4), 78 for (2), 91 for (3) and 95 for (5).
