How Can I Find Information on COD and International Standards for Water Quality?

Click For Summary
SUMMARY

This discussion focuses on the Chemical Oxygen Demand (COD) in water quality analysis, specifically addressing its components: concentration (mg/L) and light absorbance rate (A). The user seeks information on the light absorbance rate and international standards for water quality, including COD, Biological Oxygen Demand (BOD), and Dissolved Oxygen (DO). Resources mentioned include InterLab Supply for BOD testing and PolySeed for related products. The conversation highlights the need for reliable sources to obtain international water quality standards.

PREREQUISITES
  • Understanding of Chemical Oxygen Demand (COD) and its components
  • Familiarity with Biological Oxygen Demand (BOD) and Dissolved Oxygen (DO)
  • Knowledge of international water quality standards
  • Basic research skills for sourcing scientific information
NEXT STEPS
  • Research the light absorbance rate in relation to COD measurement techniques
  • Explore international water quality standards from organizations like the UN and EU
  • Investigate the methodologies for measuring BOD and DO
  • Review resources on water quality testing equipment, specifically from InterLab Supply
USEFUL FOR

Students in environmental science, researchers in water quality, and professionals involved in water testing and compliance with international standards.

Hi everyone:
I am doing my Chemistry group project right now, it is something about the water quality. And I am in charge of the COD (Chemical oxygen demand) part. The teacher told me that COD contains two parts: concentration (mg/L)and light absorbance rate (A)...something like that (I translated it from Chinese). But I didnt found any related information about the "light absorbance rate" on the internet. Can anyone give me some information about COD?
Also, can someone tell me how can I get the international standards (or standards of other countries, or organizations such as UN or EU) of water quality (COD, BOD, DO...etc)? Thanks a lot!

Wow, right above me, I just had a link "Biological oxygen demand", linking to www.polyseed.com[/url]. Now my second window has been directed to [url]http://www.interlabsupply.com/[/URL], where it says:

Welcome to InterLab Supply, your complete source for BOD testing and home of the "Original" PolySeed

Well, there ye have at least something to start with :wink:
