Amino-Functionalized Titanate Nanotubes: pH and Kinetic Study of a Promising Adsorbent for Acid Dye in Aqueous Solution

NaTiNT. u22122NH] and 3-[propyl]propyltrimethoxysilane, NaTiNT]u22122NH] and 3-[2-ethylamino]propyltrimethoxysilane, NaTiNT, NaTiNT]u22123NH; and 3-[3-propyl]propyltrimethoxysilane, NaTiNT u22123NH; NaTilane, NaTiNT]propyl]propyl]propyl]propyl]propyl]propyl]propyl]propyl]propyl]propylamino [3-ethoxysilane, NaTilane, NaTilane; NaTilane;u22123NH; The incorporation of the aminosilane groups on NaTiNT's surface has been confirmed, but it was determined that the crystalline and morphological features of the NaTiNT were retained after functionalization; spectroscopies revealed that aminosilane interacted covalently with the surface of NaTiNT; and protonografts revealed that the crystalline and morphological features were retained after functionalization.

Development of a novel method for investigation the uptake behaviors of acid dye on silk fabric at various flow statuses in a coloration circular pipe

The silk fabric's dye uptake patterns were significantly different when the coloration flow status was in laminar, transitional, and turbulent flow, respectively. In addition, decreasing the bath pH value and raising the temperature of the dyeing bath had a significant positive effect on the dye uptake behavior in several flow statuses. The results also show that the developed method and self-built fluid dynamics coloration system are able to determine dye uptake activity in various flow statuses, and that they can be useful in the development of a more effective process and parameters for cleaner textile coloration.
