“…The Redlich-Peterson model gave the best fit for the sorption process. Indeed, the value of β (1.078) is closer to unity than 0, which means that the isotherm is closer to the Langmuir than to the Freundlich model [43]. Furthermore, the Jovanovic model also showed relatively good fitting results ( R 2 = 0.899 and χ 2 = 2.583) and confirms the probability of some mechanical contacts between the adsorbate and adsorbent [44].…”

The marine environment is constantly at risk of pollution by hydrocarbon spills that requires its cleanup to protect the environment and human health. Posidonia oceanica (L.) (PO) beach balls, which are characteristic of the Mediterranean Sea and abundant on the beaches, are used as biosorbent to remove hydrocarbons from the sea. The impact of several factors such as oil concentration, time sorption, and weight sorbent was investigated to determine the oil and water sorption capacity for raw and milled P. oceanica fibers. The study of kinetic models for initial crude oil concentration of 2.5, 5, 8.8, 10, 15, 20, 30, and 40 g/L revealed that crude uptake followed the pseudo-first-order model while, for isotherm models, the crude uptake onto the P. oceanica tended to fit the Langmuir model. Experiments were performed according to two systems: a pure oil and pure water system and a mixed oil/water system. For the dry system (pure oil and pure water), the maximum oil and water sorption capacity of raw and milled fibers was found to be 5.5 g/g and 14 g/g for oil and 14.95 g/g and 15.84 g/g for water, respectively, whereas, in the mixed oil/water system, the maximum oil and water sorption capacity was estimated as 4.74 g/g, 12.80 g/g and 7.41 g/g, 8.31 g/g, respectively. The results showed that, in spite of their absorbency of a lot of water, the milled fibers with grain size ranging between 0.5 mm and 1 mm might be the relevant sorbent for the elimination of crude oil from seawater thanks to its efficient sorption capacity and low cost.

“…Though Thuja orientalis is a common tree of high altitude which has rich biomass as dry leaves, it has been hardly studied for its use. The literature review reveals that there is some work on the use of its cone as adsorbent, but the leaves have not been explored for any such use though the plant is far rich in leaves than cones [35,36]. Although many studies are available on the removal of RBBR, adsorptive removal of this dye by activated charcoal from leaves of Thuja orientalis is not yet reported.…”

Anthraquinone dyes are one of the major water pollutants due to their stability and persistence in the aquatic system. The present study describes the use of activated charcoal prepared from Thuja orientalis leaves (ACTOL) as an adsorbent to remove reactive anthraquinone dye Remazol Brilliant Blue R (RBBR) from its aqueous solution. In this work, leaves of the plant were carbonated to get fine charcoal which was activated by acid treatment and analysed by BET, SEM and FTIR techniques. Batch experiments were conducted to study the effect of pH, contact time, concentration and amount of adsorbent on the removal of RBBR in the concentration range 0.1-6.65 m mol L −1 . The highest efficiency was found to be 81% at pH 6 and contact time of 300 min. Adsorption data were analysed by Langmuir, Freundlich and Temkin isotherm models. The adsorption was found to follow Freundlich adsorption isotherm (R 2 = 0.9972). The kinetic study of the process was done by analysing the time adsorption data with pseudo-first-order, pseudo-second-order and intraparticle diffusion models, and it was found to obey pseudo-second-order kinetics. The adsorbent showed 73% of efficiency even after four regeneration cycles. FTIR analysis revealed that the various groups present at the surface of adsorbent were responsible for uptake of dye molecules. This study reveals that leaves of Thuja orientalis, a common biowaste, can be used as an efficient adsorbent for the removal of RBBR dye from its aqueous solution. It provides an economical and eco-friendly way to mitigate the waste and use it as an adsorbent.
