the data involving the 3.45 p band fit a least squares plot is not as good as that shown in Fig_ I. It is rccoInmen(led that the 5.88 &Io.g8 p ratio be used for this method of carboxyl content estimation in ruhher copolymers.
Wl~ilc tllc study was made primarily for the purpose of quickly and easily de~crminin~ the EPI-Iii value of raw material rubber, it is possible that the mcthocl mi@t also be used as an in-process check on the clegrec of polymerization of this type of copolynicr.

An amplification method has been described for the determination of chromium in low alloy steel samples. The well-known Leipert reaction has been coupled with a precipitate exchange reaction between lead iodate and chromium(III)-EDTA complex for amplification. Chromium is determined indirectly by de
A rapid, simple, and reproducible method for determination of iron in biological material is suggested using the oxidation of p-phenetidine hydrochloride with hydrogen peroxide in a reaction catalyzed by Fe(lII) and activated by f,lO-phenanthroline. The high sensitivity of the reaction allows a sing
