Sets out a flame atomic absorption method for the determination of manganese in natural and waste waters in the range of 0.005 mg/L to 5 mg/L. Manganese in the range of 0.05 mg/L to 5 mg/L can be determined by direct aspiration while the range 0.005 mg/L to 0.05 mg/L requires a pre-concentration step.RECONFIRMATION NOTICETechnical Committee EV-008 has reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.Certain documents referenced in the publication may have been amended since the original date of publication.
