초록

수용성 poly(sulfonated styrene-co-acrylic acid)를 합성하여 Cu(II)이온과의 착물형성에 관한 연구를 수행하였다. poly(sulfonated styrene-co-acrylic acid)-Cu(II)착물의 생성반응에 있어서 pH 변화에 따른 UV-Vis. 흡수 스펙트라 및 점도 특성을 시험하여 착물형성조건을 검토하였다. 또한, poly(sulfonated styrene-co-acrylic acid)-Cu(II) 착물의 생성상수와 안정도상수를 Bjerrum 방법으로 구하였고 Ringbom 방법으로 착물생성 엔탈피, 자유에너지 및 엔트로피 변화 등 열역학적 특성값을 구하였다.

Water soluble poly(sulfonated styrene-co-acrylic acid) was polymerized with sulfonated styrene and acrylic acid in the presence of silver sulfate at $99^{\circ}C$ for 4 hrs. The complex formation of poly(sulfonated styrene-co-acrylic acid) with Cu(II) was carried out. The maximum absorption wavelength of the poly(sulfonated styrene-co-acrylic)-Cu(II) system at different pH values was observed at 274 nm and 295 nm. The reduced viscosity of the poly(sulfonated styrene-co-acrylic acid)-Cu(II) complex were measured in the various pH ranges. The formation constants and stability constants of poly(sulfonated styrene-co-acrylic acid)-Cu(II) complex were calculated from Bjerrum method. The changes of enthalpy, free energy and entropy in the above reaction were determined by Ringbom method.
