calcCOD: Calculate COD'

Description

calcCOD is used to calculate the oxygen demand ('calculated oxygen demand', or COD' as described by Rittmann and McCarty (2001)) of a compound.

Usage

calcCOD(form)

Arguments

form

a chemical formula, as a character vector of length one, e.g., "C6H12O6" for glucose or "CH3COOH" for acetic acid. Not case-sensitive for single letter elements (see 'Details').

Value

• A numeric vector with COD' per g of compound.

concept

• chemical oxygen demand
• biogas

Details

Based on Eqs. (2.2) and (2.3) in Rittmann and McCarty (2001) (p 128), but using molar mass calculated with molMass. calcCOD is not case-sensitive as long as all elements have single letter abbreviations.
