“…Nowadays, innovations in treatment techniques and materials include cation/anion exchange (Pai et al, 2021), biodegradation (Varjani et al, 2020), chemical coagulation (Iwuozor, 2019), catalyst reduction (Menon et al, 2021), adsorption (Rápó et al, 2020), and hybrid materials are proposed (Imgharn et al, 2022). Adsorption was established as a favorable technique because of its simplicity, low cost, and effectiveness (Crini, 2006;Yang et al, 2022). Popular adsorbents that are generally used include activated carbon, graphene, zeolites, polymers, layered double hydroxides, and clay-bentonite (Funes et Natural material improvement has been raised as an urgent research topic for obtaining an eco-friendly material for wastewater treatment.…”

Modification of Java bentonite assists by the multi-step intercalation of sodium and ammonium ions under lowtemperature preparation. The adsorbent was examined to remove rhodamine B and methylene blue dyes in an aqueous solvent. The analysis of structural changes conducted by XRD analysis showed the peak shifting from 19.89° to 16.1° and specific peak spectra FTIR of 2846.93 cm -1 due to increase basal spacing from ammonium intercalation. The total capacities of NH-bentonite, Na-bentonite, and Natural Bentonite adsorption to rhodamine B were 192.308 mg/g, 136.936 mg/g, and 116.279 mg/g, respectively, under acidic conditions. Furthermore, the total capacities of NH-bentonite, Na-bentonite, and Natural Bentonite adsorption to methylene blue were 270.27 mg/g, 158.73 mg/g, and 136.986 mg/g, respectively, under alkaline conditions. The adsorption mechanism described that the rhodamine B and methylene blue removal occurred endothermically, was feasible, and adhered to the kinetics model of pseudo-second-order and Langmuir isotherm. It concluded that the modified Java Bentonite from multistep intercalation is affordable and effective as wastewater treatment.

Zeolit merupakan salah satu mineral aluminosilikat yang banyak dipelajari sebagai material penjerap untuk pengelolaan limbah cair. Mineral ini juga banyak dipelajari untuk pengelolaan limbah cair dari industri nuklir, termasuk di antaranya sebagai penjerap uranium dari limbah cair. Pengelolaan limbah cair yang mengandung uranium ini diperlukan pada setiap tahapan daur bahan bakar nuklir. Modifikasi zeolit, yang dapat dilakukan secara fisika atau kimia, telah dilaporkan dapat meningkatkan kemampuan adsorpsinya. Dalam penelitian ini dilakukan peningkatan kemampuan zeolit dengan menambahkan ammonium dihydrogen phosphate (ADP) sehingga terbentuk komposit ADP/zeolit untuk adsorpsi uranium. Tujuan penelitian ini adalah untuk mempelajari kemampuan komposit ADP/zeolit sebagai penjerap uranium dari limbah cair. Zeolit alam dari Lampung digunakan sebagai material awal. Material komposit dipreparasi dengan mencampurkan ADP dan zeolit dalam labu didih. Komposit ADP/zeolit yang diperoleh dikarakterisasi dengan XRD dan selanjutnya digunakan untuk percobaan adsorpsi uranium yang dilakukan dengan metode batch. Hasil penelitian menunjukkan mineral utama pada zeolit yang digunakan adalah klinoptilolit. Keberhasilan preparasi komposit ADP/zeolit dibuktikan melalui pola difraksi XRD. Hasil eksperimen ditunjukkan dengan kinetika adsorpsi uranium oleh komposit ADP/zeolit yang berlangsung cepat dan mencapai kesetimbangan kurang dari 16 menit. Model kinetika adsorpsi uranium oleh komposit ADP/zeolit model pseudo-orde kedua. Variabel pH menunjukkan adsorpsi uranium nitrat oleh komposit ADP/zeolit optimum pada pH 7. Komposit ADP/zeolit menunjukkan peningkatan kemampuan adsorpsi terhadap uranium dibandingkan dengan zeolit alam. Komposisi penyusun komposit ADP/zeolit didapatkan pada perbandingan ADP : zeolit masing-masing adalah 1:1.Kata kunci: Komposit, zeolit, ammonium dihydrogen phosphate, uranium terlarut, adsorpsi.

On the global level, uranium is considered the main nuclear energy source, and its removal from terrestrial ores is enough to last until the end of the current century. Therefore, a major focus is attracted toward the capture of uranium from a sustainable source (seawater). Uranium recovery from seawater has been reported over the last few decades, and recently many efforts have been devoted to the preparation of such adsorbents with higher selectivity and adsorption capacity. The purpose of this review is to report the advancement in adsorbent preparation and modification of porous materials. It also discusses challenges such as adsorbent selectivity, low uranium concentration in seawater, contact time, biofouling, and the solution to the problems necessary to ensure a better adsorption performance of the adsorbent.
