For the study, eucalyptus and casuarina trees were felled from the research plots established in Forest College and Research Institute, Mettupalayam (Lat. 11°19′25.37’’ and Long. 76°56′8.84’’), Tamil Nadu, India. The logs collected from the felled trees were chipped using a pilot chipper and then graded using vibrating chip classifier to get uniform sized (about 2–3 cm long) wood chips. Then the wood chips were subjected to washing to remove impurities. After washing the wood chips were dried under atmospheric conditions for 2 weeks and then stored in air tight container for further use. Chemicals such as Sodium hydroxide, Sodium carbonate, Sodium sulphide, Oxalic acid, Acetic acid and Sodium chlorite were obtained from Sigma-Aldrich, India. All the chemicals used were of Analytical Reagent grade (AR grade) and used as received.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
