TLDR
The discharge of dyes in aquatic system has horrible health and esthetic impacts, needs to be expelled from nature as mentioned in this paper. But it is difficult to find a suitable solution to this problem.Abstract:
Dyes are developing as a dangerous category of toxins to the ecosystem. The discharge of dyes in aquatic system has horrible health and esthetic impacts, needs to be expelled from nature. I...read more

Magnetic metal oxide-organic framework material for ultrasonic-assisted sorption of titan yellow and rose bengal from aqueous solutions
TL;DR: In this paper, the authors compared the sorption properties of TF and MTF under both mechanical agitation and ultrasonic treatment, and found that the maximum sorption capacity of TF was comparable to MTF, while the affinity of MTF was higher than TF for both dyes.

Correlation of diffusion coefficients in dilute solutions
Charles R. Wilke,Pin Chang +1 more
TL;DR: In this paper, the relation of P to conveniently available properties of dilute solutions is generalized to permit estimation of diffusion coefficients for engineering purposes for convective transport due to volume changes on mixing is negligible and other possible modes of mass transfer are not operative.
