Bentonite-OPBA nanocomposite has been made. The preparation of OPBA and bentonite was carried out by calcination process at a temperature of 700oC for bentonite and 500 °C for OPBA and a ball mill process for 10 hours and coprecipitation method with a solution 6 M HCl. Then nano bentonite was synthesized with surfactant Cetyl Trimethyl Ammonium Bromide (CTAB). The XRD analysis obtained a Bentonite-OPBA particle size of 14.46 nm, with a Tetragonal crystal system and density of 3.01200 g/cm3. XRF analysis obtained SiO2 content of 55.1 % FTIR analysis obtained absorption band detected at 981.33 cm−1 indicates that the increase in silica strengthening has in the polymerization process.

This research wasaccomplished to appraise the performance of Cyperus Rotundus Stalk (CRS) in adsorption of lead heavy metalofaquatic environments. For this purpose, the batch system was used for review the effect pH, Mixing time, adsorbent particle size and temperature for Pb(II) removal on the CRS. The highest lead removal efficacy was achieved in pH=6 and it was considered as the optimum pH. The result indicated the maximum Pb(II) adsorption at the contact time of 90 min which implies that increase in contact time lead to a higher lead uptake.The amount of R2using the pseudo-second-order are greater than compare with others models.Influence of temperature was determined byusing thermodynamic parameters and the results showedremoval of lead on the CRS was endothermic, spontaneousandfeasible.

“…Its fast absorption and high adsorption capacity, coupled with its natural abundance in the environment, is a low-cost adsorbent that can be used in various wastewater treatment applications (Ginting, Bukit, Motlan, et al Natural agro minerals, such as bentonite have unique catalytic and adsorption properties. Bentonite is one of the most promising types of materials as a safe nanotechnology material (N. Bukit et al, 2018;Sirait et al, 2017Sirait et al, , 2018Toor et al, 2015). The adsorption ability of natural bentonite is not realized to its full potential when no modification is made.…”

Using the products derived from agricultural wastes as low-cost adsorbent materials to remove organic or inorganic contaminants would be ideal, as these materials are readily available in many countries. This study aimed to prepare environmentally friendly adsorbents made from nanocomposite OPBA / Bentonite / TiO 2 . The coprecipitation method was used in preparing OPBA, and CTAB surfactant was added in bentonite preparation. Meanwhile, the manufacture of TiO 2 was carried out using the sol-gel method. Characterization was done by XRD, FTIR, SEM, and BET. The adsorbent spectra did not show a significant shift in absorption where the O-H bonds were becoming weaker due to the presence of TiO 2 in the interlayer of bentonite. Another possibility is due to the influence of calcination and heating. The O-H groups of H 2 O are hydroxylated and dehydrated from within between layers. The formation of the composite OPBA/TiO 2 /Bentonite does not change the crystallinity of TiO 2 significantly. This proves that there is no decrease in photocatalyst activity after the addition of OPBA and bentonite. The morphology of the whole sample has a flake-like structure that has pores. The addition of OPBA into Bentonite/TiO 2 causes a decrease in the specific surface area of the sample.
