標(biāo)準(zhǔn)簡(jiǎn)介：This standard specifies a method of the determination of primary biodegradabilty of surfactants by aerobic micro-organisma. This standard is applicabl to determination of biodegradability of anionic surfactants characterised by sulphate and sulphonate group;polyoxyethylene nonionic surfactants characterised by single EO chain with EO number ranging from 3 to 40,or multi EO chains(double,triple,quadruple EO chains)with total EO number ranging from 6 to 60;alkyl polyglycoside surfactants;cationic and amphoteric surfactants and surfactants capable of producing rich foam during test.This standard is also applicable to determination of the biodegradability of above surfactants in detergents.
