Quantitative determination of methanol in plant water produced in Mashhad by spectrophotometry method

Methanol is a toxic aliphatic alcohol that is widely used in industry as a solvent. Poisonings occur from accidental or awareness ingestion of it. In this study, the amount of methanol in ten plant water was evaluated. Five samples from each plant waters that related to six factories collected and analyzed by spectrophotometric method. The results showed that the highest [1477.7 +/- 23.8 ppm] and the lowest [79.4 +/- 3 ppm] amount of methanol was related to dill and egiptial willow water, respectively. Since, the chronic use of plant water may induce methanol toxicity, it is recommended to determine a safe limit for it
