Webp-Nitrophenol (0.3 pmole) was incubated for 30 min in MciLVAINE buffer with 0.5 g of different soils and assayed as described for PNG hydrolysis. The amount (0.3 pmole) of p-nitrophenol added was similar to that released from PNG by 0.5 g of soil in present experimental condition. Table 2 shows that recoveries of p-nitrophenol by ethanol ex WebPesticide sensing is an important object of study due to its increasing use worldwide. Herein, we report a SERS study of 4-nitrophenol (PNP), which is product of neutralization processes of various pesticides such as Paraoxon, and can be used as a target molecule for monitoring. PNP is also widely used in th
