In this article, Cr(OH) nanoparticle-modified cellulose nanocrystal (CNC) as a novel hybrid nanocomposite (Cr(OH)-NPs-CNC) was prepared by a simple procedure and used as a sorbent for adsorptive removal of methylene blue (MB) and malachite green (MG) from aqueous solution. Different kinetic models were tested, and the pseudo-second-order kinetic model was found more suitable for the MB and MG adsorption processes. The BET and Langmuir models were more suitable for the adsorption processes of MB and MG.

- A new method was created for accurately measuring methylene blue dye in solutions using a combination of dispersive solid phase and cloud point extraction with Cu(OH) nanoflakes.
- The process involves adsorbing the dye onto the nanoflakes, which are then transferred into a surfactant-rich phase with Triton X-114, and finally analyzed using UV-Vis spectrophotometry.
- The method proved effective across various conditions and water samples, with a strong calibration and detection capabilities, demonstrating reliable results confirmed by statistical analysis.
