摘要：
The binding of evans blue, a bisazo dye used in blood volume determination, onto poly(N-vinyl-2-pyrrolidone) was studied using Klotz's spectrophotometric method. Addition of NaCl decreased the binding constant due to competitive binding, whereas ureas enhanced the binding due to conformational transition. Analysis showed that electrostatic interaction was the predominant force while hydrophobic bonding was less significant.
