Overview

The revolutionary applications of seaweed extracts show promising potential to change the way of research and commercial applications based on seaweed. A commercial liquid extract (True Algae Max, TAM ® ), derived from three seaweed species ( Pterocladiella capillacea, Jania rubens , and Ulva lactuca ), contains a variety of several nutrients, bioactive compounds, and biomolecules, thereby exhibiting potent biological activities. Due to their extensive industrial use, organic dyes constitute a substantial constituent of wastewater. The adsorption process of anionic methyl orange (MO) dyes onto TAM ® in an aqueous solution as a potential and a new adsorbent has been investigated. Energy dispersive X-ray spectroscopy (EDS), Mass spectra, and Infrared analysis (FT-IR) were applied to verify the adsorption performance. Batch adsorption experiments were performed to estimate the influence of several factors such as pH, the amount of TAM ® sorbent, temperature, agitating time, and initial concentration of MO dye parameters. Maximum dye adsorption of 90.34%and 46.09 mg g –1 was recorded at doses of biomass at 0.4 g and 16.88 mg g − 1 at pH 1. Adsorption kinetics data were investigated by the first, pseudo-second-order, and intraparticle diffusion models. Kinetic studies showed that the adsorption process was followed by intraparticle diffusion models and a pseudo-second-order reaction. The investigational isotherm data were studied using four isotherm models to evaluate the adsorption equilibrium using regression analysis. With maximum sorption capacities of 156.25 mg g − 1 for MO. Regeneration of the consumed adsorbent was effectively emphasized for two cycles of desorption/sorption process for MO removal from the aqueous solution. According to the findings, TAM ® biomass is a novel, inexpensive alternative adsorbent that shows promise for removing MO from aqueous solutions. Additionally, the usage of TAM’s methanol extract exhibits substantial antibacterial action at concentrations of 500 mg ml − 1 against Staphylococcus aureus, Salmonella typhimurium , and Pseudomonas aeruginosa , and 250 mg ml − 1 against Escherichia coli .
