Sir how much sample volume should we take? Is it necessary to make it light green or not because some people on internet use green sample and some use orange sample like BLANK one?

Sir, iam from Tami Nadu and I could understand a little but if you post videos teaching in English it will be very useful for other language students also !!! Just a kind request.
Sir your definition is wrong. It must be the total amount of oxygen required to chemically oxidise the biodegradable and non-biodegradable organic matter under strong oxidising agent such as K2Cr2O7. It is not the capacity of water
Congratulations Sir for a nice explanation Can we use Cupric sulphate instead of HgSO4..to avoid toxicity.. My another doubt is this method hazardous ..what are the safety requirements we taken care of bcoz am working in this field..
Sir Agar, BOD and COD Organic matter pe depend karta hai to jis taraha COD ka converting factor hai us tarha BOD ka converting factor hoga? So if you have any BOD converting factor so please give me TOC to BOD converting factor

U can use the hot plate or heater instead of cod diegester with round bottom flask or iodine flask.
Or may be hot air oven
