초록

채취한 양식진주를 불순물 제거와 표면표백을 통해 염색이 용이하도록 전처리하였다. 전처리된 양식 진주의 표면은 해수로부터 형성된 경단백질의 일종인 Conchiolin 막으로 덮혀있기 때문에 Conchiolin 층에 흡착이 가능한 염료를 선택하여 상품으로 원하는 색상을 흡착하는 공정이 필요하다. Conchiolin 층에 흡착 가능한 염료들은 Rhodamine 6aG(R6G), Rhodamine B(RB) 및 Methylene Blue(MB) 등의 염기성 염료들이 주류를 이루고 있으며 이들 염기성 염료를 선택하여 각각 이성분 및 삼성분으로 염색용액을 제조하여 경쟁흡착 실험을 수행하였다. 이성분 및 삼성분 경쟁흡착의 친화도는 단일성분 흡착 model 인 Langmuir 혹은 Redlich-Peterson(RP) model과 결합된 ideal adsorbed solution theory(IAST)를 이용하였으며, 흡착자료와 IAST 예측치의 차이를 $R^2$ 및 SSE 값으로 판단하였다. 결과적으로 분급되지 않은 진주층에 대한 R6G와 RB의 경쟁흡착의 경우에는 IAST 예측치는 실험값과 잘 일치하고 있으나, 분말상 진주층의 경우, 높은 농도에서의 RB는 실험치와 예측치가 일치하고 있지 않음을 알 수 있었다. 분급된 진주층의 경우에도 R6G/RB, R6G/MB, MB/RB에서 이성분계 혼합용액의 이성분 경쟁흡착에서 R6G/RB의 경우에만 RB는 잘 일치하지 않음을 확인되었다. 삼성분계의 경우에도 RB를 제외하고는 실험치와 예측치가 잘 일치하고 있었다.

The cultivated pearls collected for the study were pretreated through the removal of contaminants and the surface bleaching for easy dyeing. Coloring of pearls are necessary after selecting dyes adsorbable to the Conchiolin layer, a kind of hard protein formed in the seawater, covering the surface of the pretreated pearls. Dyes adsorbable to the Conchiolin layers are mostly basic dyes such as Rhodamine 6G(R6G), Rhodamine B(RB), Methylene Blue(MB) etc. and the binary and ternary competitive adsorption were performed by mixing two or three dyes together. The multi-dye adsorption data were compared with the predictions from the ideal adsorbed solution theory(IASI) combined with the single-dye adsorption model, the Langmuir or the Redlich-Peterson(RP) model. The quality of prediction was compared by using determination coefficient($R^2$) and standard deviation(SSE) values. Predictions from the IAST were found to be in good agreement with the data for the R6G/RB binary adsorption to the pearl layers not fractionated with their size, except for the adsorption data for RB at high concentrations. Among the three binary adsorption systems, R6G/RB, R6G/MB, and MB/RB, only the RB sorption data in the R6G/RB binary system was in poor agreement with the IAST prediction. Competitive adsorption data in ternay systems were in good agreement with the predictions from the IAST except for the RB data.
