Descripción

Aplicación

• Fixed-Bed Column Studies: Continuous fixed-bed column studies utilize Congo red to investigate the adsorption capabilities of various natural adsorbents, such as Nelumbo nucifera (lotus) leaf adsorbent. These studies help in understanding the dynamics of dye removal in real-world applications, providing valuable data for scaling up adsorption processes for industrial wastewater treatment (Vairavel and Rampal, International Journal of Environmental Analytical Chemistry, 2021).


• Nanocomposite Adsorbents: Congo red is used in studies involving nanocomposite adsorbents, such as calcined ZnAl-LDH (layered double hydroxides) trapped in alginate beads. These studies explore the adsorption efficiency, regeneration, and reusability of nanocomposites for removing dyes from water, contributing to the development of advanced materials for environmental cleanup (El Khanchaoui et al., International Journal of Environmental Analytical Chemistry, 2021).
