“…The Archimedes principle method showed that the porosity was about 30%, which is a value high enough to get efficient membranes for filtration. This porosity was created by incorporating the rice husk material in the clay before heat treatment [2] [16]. Table 2 shows the influence of mixture proportions and size of clay and rice husk on shrinkage (percentage of thickness diminution after firing), we observed that when the clay granulometry is ≤50 µm and rice husk granulometry is ≤50 µm, the shrinkage was 46%.…”

This paper deals with the characterisation and study of physico-chemical stability of ceramic filters from clays and rice husk obtained from the far north region of Cameroon (Logone Valley) and their application in potable water treatment. Clays from Mouka were characterized by FTIR analysis. The results showed that the filter formulated with a mixture containing 80% clay and 20% rice husk of 100 μm in size each gave the lowest filter shrinkage rate; these formulated filters were chosen for the remaining work. Leaching tests showed that with filters at a sintering temperature of 830˚C the leaching was not observed under neutral (pH 6.8) and acidic (pH 5) conditions as compared to 950˚C and 1000˚C where the leaching was observed. In basic (pH 9) condition, all the filters obtained released ions. Leaching tests revealed that the conductivity of the leachate for the filters sintered at 830˚C was lower than those sintered at 950˚C and 1000˚C. Meanwhile, conductivity decreases with increasing sintering temperature (temperature up to 830˚C) due to the fact that ceramization starts as from 850˚C that leads to an amorphous state that favours chemical stability, the leaching ions were Fe 2+ , Ca 2+ , Mg 2+ and Al 3+. The ceramic filters sintered at 950˚C were applied to the filtration of water and the performance in terms of turbidity reduction was 95% and the flow rate after 50 minutes was 100 × 10 −3 L/h.

The contamination of environmental matrices by chemical compounds poses a significant challenge for humanity, demanding focused attention from researchers and governments. Within aquatic environments, the emerging contaminants with potential ecotoxicological effects, even at low concentrations, have earned global interest among researchers. The persistence of these contaminants is exacerbated by specific physicochemical characteristics, hindering their natural degradation and removal through conventional water treatment methods. Biochar, a carbonaceous material produced through biomass pyrolysis at high temperatures, exhibits properties that effectively remove emerging contaminants from water. In this study, we investigated the impact of acidic biomass treatment on the removal efficiency of ivermectin from aqueous solutions. The materials were derived from untreated biomass, as well as basic and acidic-treated peanut shell (PS), subjected to pyrolysis at temperatures of 300, 400, 500, and 600 °C for 2, 3, and 4 hours. Characterization was conducted using TGA, ATR-FT-IR, SEM-EDS, and XRD. Quantification of ivermectin removal was performed using HPLC-DAD. The results showed that the removal was enhanced by temperature and time of pyrolysis, while the chemical treatments had different effects. The most effective removal tendency was observed with acidic biochar calcinated at 600 °C, demonstrating an average removal yield of 84.70%.

“…Temuan ini diperkuat dengan temuan sebelumnya yang menyatakan pembuatan keramik berpori menggunakan tepung jagung membuat pori yang menyeluruh (Mohamed Bazin et al, 2019). Kandungan tepung jagung yang lebih banyak akan membuat keramik berpori jadi lebih baik dan lebih banyak porinya (Alag & Zamel, 2018;Ayala-Landeros et al, 2016;X. Liu et al, 2022).…”

Separator baterai yang terbuat dari keramik zeolit telah dilakukan. Separator ini dimungkinkan menjadikan baterai yang stabil dan tahan lama. Pada penelitian ini mencoba membuat elemen sel baru menggunakan keramik berpori yang terbuat dari campuran serbuk zeolit dan tepung jagung sebagai pengganti separator. Proses persiapan bahan dengan pengayakan serbuk zeolit dan tepung jagung dengan ayakan mesh 30. Serbuk zeolit ditambahkan 2, 5 dan 8 % berat tepung jagung. Bahan serbuk zeolit-tepung jagung dicetak berbentuk prisma segi empat dengan tekanan 15 MPa. Green keramik dibakar dengan furnace selama 4 jam dengan suhu 900 ⁰C. Keramik berpori di assembling ke baterai bersama anoda katoda kemudian dirangkai secara seri. Cairan sebesar 10 ml digunakan untuk mengisi rongga keramik berpori tersebut. Hasil pengujian tegangan listrik menunjukkan semakin tinggi penambahan tepung jagung semakin rendah voltase yang dihasilkan. Berdasarkan pengujian secara visual dan mikro di dapat bahwa semakin banyak persentase campuran tepung jagungnya maka semakin banyak pula pori yang terdapat pada keramik serta mengurangi kerapatan pada keramik.
