The principal aim of this present research was to analyze how the variation in the percentage of Sansevieria trifasciata fibers and the contact time affects the removal efficiency of chromium (VI) in simulated wastewater effluent solutions. The methodology included physical-chemical aspects, using techniques such as Fourier transform infrared spectroscopy (FTIR) and optical microscopy to characterize the fibers, as well as measurements of chromium (VI) concentration using the UV-visible spectrophotometric method. The experimental design, with an explanatory and quantitative approach, contemplates different percentages of fibers (1%, 5%, 10%) and contact times (30, 60 and 90 minutes). As a result, significant variations in chromium (VI) removal efficiency were observed depending on the percentage of fibers and contact time. It was determined that the higher percentages of fibers demonstrated a more pronounced adsorption capacity, suggesting a direct relationship with the greater availability of active sites in the biomass. Likewise, it was evident that the contact time influenced the adsorption kinetics, allowing a continuous improvement in the removal of chromium (VI) by increasing the duration of the test. Obtaining a maximum removal percentage of 98.65% through the optimal contact time of 90 minutes and the optimal percentage of Sansevieria trifasciata fibers of 10%. In conclusion, this research highlights the joint influence of the percentage of fibers and contact time on the removal efficiency of chromium (VI), providing valuable information for the efficient design of adsorption systems in the treatment of wastewater contaminated with this metal. heavy.
