Rapid determination of methanol in herbaceous distillates for their safety evaluation by a new modified chromotropic acid method
All sophisticated methods for direct determination of methanol require advanced instruments and high technical knowledge which preparing them is very expensive in none developed and developing countries. This work reports a simple and efficient qualitative technique for semi determination of methanol content in herbal distillates by a new modified chromotropic acid method. The technique is base...

متن کاملDetermination of Methanol Content in Herbal Distillates Produced in Urmia Using Spectrophotometry
ABSTRACT Background: Herbal distillates have been used for many centuries as drinks, flavors, and herbal medicine in Iran, especially in the city of Urmia. Recently, some studies claimed the presence of methanol in different types of herbal distillates. Methanol is a highly toxic compound which can cause acute or chronic toxicity in humans. Acute poisoning with methanol can cause different co...
متن کاملAdaptation of the Micro-kjeldahl Method for the Determination of Nitrogen in Plant Tissues.
The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...
