利用紫外-可见光光谱仪与共振光散射(RLS)技术研究了在控制条件下的四(4-磺酸基苯基)卟啉(TPPS)在甲壳素膜上的聚集行为.研究发现TPPS在甲壳素膜上的聚集行为强烈地依靠溶液的pH值,在pH值小于4时,TPPS在甲壳素膜上以J-型与H-型聚集体共存的形式聚集,而溶液pH值较高时,TPPS则只能以H-型聚集体的形式聚集于甲壳素膜上.图6,表1,参6.
The aggregation behavior of tetrakis (4-sulfophenyl) porphyrin (TPPS) on chitin film under controlled conditions was investigated by UV-visible spectroscopy and resonance light scattering (RLS) Aggregation behavior strongly depends on the solution pH. When the pH value is less than 4, TPPS aggregates on the chitin film in the form of J-type and H-type aggregates. When the solution pH is higher, TPPS It can only aggregate in the form of H-type aggregates on the chitin film.
