Polyvinylpyrrolidone and polyacrylamide intercalated
The isothermal sorption of Cr(VI) on the composites was investigated at 298 K, 313 K, and 328 K, respectively. As illustrated in Fig. 4, the sorption of Cr(VI) on PVP/MoS 2 (Fig. 4a) and PAM/MoS 2 (Fig. 4b) increased with the increase of temperature, implying that higher temperature can promote Cr(VI) sorption . To investigate the possible

A Review on Reverse Osmosis and Nanofiltration Membranes
1. Introduction. Human welfare has been promoted by continued economic growth, which is accounted for by mechanization and industrialization. However, increasing income and wealth would cause ecological problems, since natural resources are used as inputs of several products, and the pollution of the environment is directly linked to the production scale [1,2].
International Journal of Minerals, Metallurgy and Materials (IJMMM, ISSN 1674-4799, CN 11-5787/TF, monthly, started in 1994, formerly known as Journal of University of Science and Technology Beijing) is an international journal devoted to publishing original research articles (and occasional invited reviews) on all aspects of minerals processing, physical metallurgy, process metallurgy, and

Genetic Soil Classification of China is the attribute base for the recently assembled digital form of the 1:1 000 000 soil map of The People's Republic of China. The translation between GSCC and ST was based on profile, chemical, and physical descriptions of 2540 soil series.
The functional groups and site interactions on the surfaces of two-dimensional (2D) layered titanium carbide can be tailored to attain some extraordinary physical properties. Herein a 2D alk-MXene (Ti3C2(OH/ONa)xF2–x) material, prepared by chemical exfoliation followed by alkalization intercalation, exhibits preferential Pb(II) sorption behavior when competing cations (Ca(II)/Mg(II

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?
- However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- Can cationic polyacrylamide flocculants be used to treat oily water?
- Shu, G., Bu, K., Zhao, B. & Zheng, S. Evaluation of newly developed reverse demulsifiers and cationic polyacrylamide flocculants for efficient treatment of oily produced water. Colloids Surf.
