    Abstract: A sampler system for water contaminants. The sampler system includes an adsorptive sampler housed within a cylindrical enclosure, which has a top face, a bottom face and a cylindrical surface. The cylindrical surface of the sampler system is fluid-permeable. A cable connects the top face of the cylindrical enclosure to a flotation device. A spring connects the adsorptive sampler to the bottom face of the cylindrical enclosure. The adsorptive sampler includes a housing having a cavity and an adsorptive material disposed inside the cavity. The housing is attached to the spring and includes a front face and a back face. The spring is a cantilever in the form of a rigid film, wherein the rigid film is connected to the bottom face of the cylindrical enclosure along a flat edge of the rigid film.

    Abstract: A sampler system includes an enclosure having a top, a bottom and a sidewall that is fluid permeable. The sampler system further includes a sampler apparatus housed within the enclosure. The sampler apparatus includes a sampling component having a support structure and an adsorbent. The sampler apparatus further includes an oscillating component including a spring which connects the sampling component to the bottom of the enclosure. A retaining component includes a first magnet attached to the sampling component and a second magnet separated from the first magnet by a gap.

    Abstract: A biochar-derived adsorbent preferably from Sargassum boveanum, macroalgae can be used for removing phenolic compounds, such as 2,4,6-trichlorophenol and 2,4-dimethylphenol, from aqueous solutions. The carbonization can improve the removal capability of the macroalgae adsorbent for such phenolic compounds with removal efficiencies of 60% or more from high salinity seawater and 100% from distilled water. The adsorption may occur through a mixed mechanism dominated by physisorption following pseudo second-order kinetics. The adsorption of the phenolic molecules may be spontaneous, endothermic and thermodynamically favorable.
