Abstract In pH 2. 7 acetate buffer solution and in the presence of Triton X 2100 , the bis (butoxycarbonylethyl) tin
dichloride ( R2 SnCl2 ) reacts with 22( 52Br222 pyridylazo )252diethylaminophenol ( 52Br2PADAP) to form a 1∶ 1
purplish red complex. The maximum absorption of the complex is at 505 nm and the apparent molar absorptivity of
the complex is 1. 05× 10
