WE have developed recently1 a method for the micro colorimetric estimation of iron as triphenyl-methylarsonium hexathiocyanato ferrate III, (Ph3MeAs)3(Fe(CNS)6), in which this compound was extracted from aqueous solution with o-dichlorbenzene in the presence of about seventy equivalents of tri-phenylmethylarsonium thiocyanate. The orange-red solution had a sharp absorption maximum at 478 mμ. (curve
