“…45,46 The observed blue-and red-shift for XN dyes by WO 3 colloid titration are resulted from the sum absorption of dimerized ones on WO 3 colloids and unadsorbed ones in the aqueous solution. Using the K'…”

The surface interactions between xanthene (XN) dyes, including rhodamine B, rhodamine 3B, rhodamine 19, rhodamine 6G, rhodamine 110, and rhodamine 123, and tungsten(VI) oxide (WO 3 ) colloid particles were investigated. These XN dyes were strongly adsorbed as monolayer onto the WO 3 surface via the electrostatic interaction between their peripheral cationic amino-substituents and negatively surfacecharged WO 3 colloid particles, and most of ones adsorbed eventually formed the stable π-stacked dimers.The geometry of dimers formed on the WO 3 colloid surface is discussed on the molecular exciton theory framework. Cationic XN dyes formed the approximately ideal face-to-face H-dimers on the WO 3 colloid surface, whereas zwitterionic ones had a higher tendency to form the oblique J-dimers. Additionally, we have experimentally demonstrated the possibility of pH-induced switching between H-and J-aggregation modes of the XN dye's dimers formed on the WO 3 colloid surface. The findings lead to a better understanding of organic dye's adsorption/aggregation behaviors on the metal oxide surface.

“…However, it seems this is not the only reason, if one compares the results presented in Table 3. It should be mentioned that the apolar and electron acceptor components for untreated Leacril surface shown in this table are somewhat different than those obtained previously (38.1 and 1.3 mJ/m 2 , respectively), while the electron donor component is practically the same (previously 52.3 mJ/m 2 ) (14). This is probably due to a different lot of the Leacril sample used in these experiments.…”

“…In our previous papers (11,13,14) the process of Leacril dyeing with solutions of a cationic dye has been analyzed for the fabrics being pretreated with a surfactant to strengthen adsorption of the dye onto the fibers. However, the obtained results showed that the adsorption was often rather weak and hence it is worth investigating possibilities to increase the adsorption strength of dye taken up by the fabric, possibly at ambient temperature.…”

“…From Table 3 it can be seen that the ζ potential values of AR 14 and AB 10 were negative. After adding CTD or CTB in acid dye water samples, the cationic groups (quaternary ammonium groups) on the surface of CTD or CTB underwent electrical neutralization with colloidal particles of the dye water samples (Espinosa-Jiménez et al 1998). Charges on the surface of the colloidal particles were close to zero and even had the opposite charges.…”

a Two particulate amphoteric larch tannin (CLT) products (CTD and CTB) were prepared by cross-linking reactions, and their acid dyes removal abilities were investigated. The effects of several parameters such as pH, contact time, and particle doses were tested, and the acid dyes removal behaviors of both types of particles were compared. The removal of azo acid dyes on CTD and CTB was pH-dependent, and the maximum removal of ≥90.7% was reached for Acid Black 10 B and 52.6% for Acid Red 14 in aqueous solution at pH 5.0. The effect of particle dosages on the removal of Acid Black 10 B and Acid Red 14 was important for two modified CLT particles. An excessive amount of modified CLT particles increased the chromaticity of water samples and caused the decline of dyes removal. Zeta (ζ) potential data revealed that the main mechanism of removal of the acid dyes on the CTD and CTB particles was charge neutralization.
