We want to estimate the HCN content in cassava roots and tubers. Ezeigbo et al (2015) mentioned the method to estimate HCN content. But, They did not mention the preparation of alkaline picrate solution. Please help us.
For alkaline picrate solution, you can use 0.5% picric acid and 2% sodium carbonate solution.
It is prepared by taking 9.16 gm of picric acid and volume is made upto 1000ml with 1N sodium hydroxide
Thank you Dr. Augustine and Dr. Manisha
