| 摘 要： | 1 Introduction Plant polyphenols are a large and diverse class of poly-atomic phenols which occur naturally in some parts of plants. Their molecular weight ranges from 500 to 3,000 g·mol–1. Plant polyphenols are abundant in nature and their production capacity is only second to that of cellulose, hemicellulose and lignin (Sun, 1988). Polyphenols can be divided into two kinds given their chemical constitution: hydrolysable tannin and condensed tannin (Song and Di, 2000). Benzene rings in th…

| Abstract: | In this paper, a new kind of adsorption resin with multi-phenolic hydroxyl was created by immobilizing black wattle bark tannins to chloromethyl polystyrene resin. Its adsorption capacity to cation dye was tested. With an orthogonal test the optimal conditions of synthesis were determined: the concentration of sodium hydroxide solution 1.0 mol·L−1; the reaction time is one hour and the mass concentration of tannins 5%. With single factorial experiment the optimal conditions of adsorption were confirmed: a solidified pH of 5.0; an adsorption temperature of 25°C and a cation dye concentration of 100 mg·L−1. The adsorption for cation dye can be similar to Langmuir isotherms. |
