Electronic spectra of the hybrid films gave absorption peaks at 600 and 656 nm, which were assigned to the dimeric MB+ and the monomeric MB+ in the film, respectively. The absorbance at 600 nm increased linearly with the increase in the layer number, indicating that the hybrid monolayers were fabricated in a layer-by-layer way. The slope of the line was dependent on the clay concentration in the suspension used for the film preparation. This meant that the density of the cationic dye in the film could be controlled by changing the clay concentration. The XRD patterns for the hybrid multilayers were independent of the clay concentration. From the XRD data, a thickness of the MB+ layer in the film was calculated to be 1.05 nm. In order to determine the molecular orientation of MB+ in the hybrid film, electronic spectra with sand p-polarized lights for the films were recorded. As a result, the long axis of the molecule was inclined at 21•‹ with respect to the film surface. Taking the thickness of the MB+ layer (1.05 nm) into consideration, a model of the molecular orientation in the film was proposed.","PeriodicalId":164792,"journal":{"name":"Journal of the Clay Science Society of Japan","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114146259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can be synthesized in mild condition, and have diversity in composition. Hydrotalcite-like compounds can serve as complementary adsorbents to smectite clays for anionic pollutants, on account of the opposite sign of balancing charge. Other than anionic substance, hydrotalcite-like compounds can capture hydrophobic pollutants after surface modification, and even cationic hazardous metal ions by diadochy. Hydrotalcite-like compounds can be catalytic supports for immobilization of watersoluble anionic catalysts, and also be precursors for environmental catalysts.
