Chelating resin as a new copolymer for metal ions removal was prepared using 3-(4-hydroxyphenyl) cyclopropane-1,1,2,2-tetracarboxylic acid and 1,2-diaminoethane on the poly(styrene-alt-maleic anhydride). Parameters of sorption behavior were investigated under various conditions. Kinetics studies revealed that adsorption process confirmed pseudo-second-order kinetics data well fitted to Langmuir...

The oxidized bitumen produced at the Ukrainian refinery was modified with maleic anhydride. process temperature proved to have most significant effect on modification. chemical interaction of anhydride components confirmed. At low temperatures (up 403 K) chemistry modification is another than carried out high temperatures. structures were established different (403, 423 and 443 using FTIR spect...
