abstract = {The management of agricultural waste is an important issue related to environment
protection, as the inappropriate disposal of this waste yields negative effects on the environment.
Proper management of industrial effluents is totally aligned with sustainable development goal
(SDG) number six “clean water and sanitation”, as well as partially related to other several SDG. In
this work, two agricultural waste materials were used for vanillic acid recovery from wastewater.
In this scenario, vanillic acid could be considered as both an organic pollutant present in several
industrial effluents and a high added-value product when isolated. Therefore, its removal from
wastewaters, as well as its recovery and isolation, are very interesting from environmental and
economical points of view. Peanut and pistachio shells were studied as no-cost and readily accessible
potential adsorbents for the removal and recovery of vanillic acid from aqueous solutions. The
evolution of equilibrium isotherms of vanillic acid on both biosorbents was investigated. Three
isotherm models (Langmuir, Freundlich, and Temkin) were tested to fit the experimental equilibrium
data and compared. The Langmuir model provided the best correlation for vanillic acid biosorption
onto both peanut and pistachio shells. Finally, the negative values of DG indicated that the biosorption
process was spontaneous and thermodynamically favorable for both agricultural waste materials.
Accordingly, peanut and pistachio shells were shown to be very efficient low-cost adsorbents, and a
promising alternative for vanillic acid recovery from industrial wastewaters.},
