Trong bài báo này, graphen oxit (GO) được tổng hợp từ bột graphit bằng phương pháp Hummer; GO khử axit ascorbic thành dạng (rGO). Titan dioxit (TiO2) cấu trúc nano có tính ổn định vật lý và hóa học cao với nhiều ứng dụng, đặc biệt là trong lĩnh vực môi trường. Vật liệu TiO2/rGO trưng nhiễu xạ tia X (XRD) hiển vi điện tử quét (SEM) để chứng minh các điểm hình thái của bề mặt chất hấp phụ. Quá tr...

The thermodynamic properties of carbonate minerals suggest a possibility for the use abundant materials (e.g., magnesite) removing harmful divalent heavy metals Pb2+). Despite favourable condition such transformation, batch experiments performed in this work indicate that kinetic magnesite dissolution at room temperature is very slow. Another set co-precipitation from homogenous solution Mg-PbI...

The potential of perennial bioenergy Miscanthus feedstock grown on heavy metal contaminated land was evaluated for the production clean renewable energy, chemicals, and recovered metals. Trace element analysis showed significant levels contaminants from harvested Miscanthus: 6.47 g Pb per kg biomass, 1.91 kg−1 Fe, 0.35 Zn, 26.59 mg Cu; along with other metals including Cr, Ni, As Cd. protic ion...

Incorporation of heavy metal ions in cement hydrates is great interest for the storage and immobilization toxic, hazardous, radioactive wastes using cementitious matrix. Magnesium silicate hydrate (M-S-H) a low pH alternative binder to commonly used Portland cement. Low cements have been considered as promising matrix municipal nuclear waste last decades. It however crucial assure that incorpor...

Precipitation of calcium carbonates in aqueous systems is an important factor controlling various industrial, biological, and geological processes. In the first part this study, well-known titration approach introduced by Gebauer coworkers 2008 s used to obtain reliable experimental dataset for deep understanding CaCO3 nucleation kinetics supersaturated solutions over a broad range pH ionic str...
