摘要
本文研究了用NH_3·H_2O—NH_4Cl—NaF—(NH_4)_2S_2O_8—DDTC沉淀分离干扰离子后,在pH9.5的NH_3·H_2O—NH_4Cl介质中,用PAR光度法测定铁矿石中的锌.
A spectrophotometric method has been developed for the determination of zinc in iron ores with PAR in pH 9.5 NHs H2O-NH4Cl medium, after seperation and settlement of interferences with NH8 H2O-NH4Cl-NaF- ( NH4 ) 2S2O8-DDTC.
