Recycling waste Styrofoam to new useful materials is essential both the environment and humans. In this paper, (Sfm) was chemically converted via nitration sulfonation procedures corresponding nitrated (Nit-Sfm) sulfonated (Sulf-Sfm) derivatives for further use as potential cation exchangers. The proposed method aimed proceed surface chemical modification without changing core of material. degrees incorporated exchange properties Nit-Sfm Sulf-Sfm adsorbents were determined found correspond...
Abstract Novel synthesized Chitosan–Copper oxide nanocomposite (Cs–CuO) was prepared using pomegranate peels extract as green precipitating agents to improve the biological activity of Cs-NP's, which through ionic gelation method. The characterization biogenic nanoparticles Cs-NP's and Cs–CuO-NP's investigated structurally, morphologically determine all significant characters those nanoparticles. Antimicrobial tested for both via minimum inhibition concentration zone analysis against fungus,...
