A cross-linked chitosan/(MnFe2O4) CCsMFO nanocomposite was prepared using co-precipitation methods and used as a nanomaterial to extract U(VI) Th(IV) from an aqueous solution based on adsorption phenomena. The contact time of experiments shows rapid extraction process within 30 min by the nanocomposite. pH acts critical role in determining qm value, where 3.0 best value both ions. pseudo-second...

in order to enhance the performance of interconnects which are used in solid oxide fuel cells (sofcs), a protective/conductive coating can be applied. in this research aisi 430 ferritic stainless steel was coated in a mn-base pack mixture by pack cementation method. in order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºc. electrical behavior was al...

Vật liệu MnFe2O4/bentonite được điều chế bằng phương pháp hóa học ướt, sản phẩm xác định nhiễu xạ tia X và đường đẳng nhiệt hấp phụ/giải phụ nitrogen. Một số yếu tố ảnh hưởng đến quá trình MB của vật như pH, nồng độ ban đầu, lượng chất phụ, thời gian khảo sát. Kết quả cho thấy, dung thuốc nhuộm tăng khi độ, tiếp xúc, pH tăng. Động trên phù hợp với mô hình động biểu kiến bậc hai. Đường tuân theo...
