Anionic polyacrylamide efficiency in goethite removal
The main aim of the study was to investigate the anionic polyacrylamide (PAM) efficiency as a flocculant relative to goethite particles. This mineral is a toxic waste produced during hydrometallurgical processes and, as a result, poses a threat to the environment. In the experiments, the following analytical methods were applied: potentiometric titration, zeta potential and adsorption amount
Rapid removal of ammonium from domestic wastewater using polymer hydrogels ammonium from domestic wastewater. Adsorption and crystallization are two possible solutions for ammonium recovery in
Rapid removal of polyacrylamide from wastewater by plasma
Profiles of PAM removal with and without co-existing organic pollutants in wastewater (PAM, 100 mg/L, discharge voltage, 25 kV, pH 7). Although the PAM after plasma treatment for 60 min was still recalcitrant to biodegradation, the TOC removal efficiencies of the PAM solution by biological treatment were 9.8% and 32.2%, respectively, after
The pseudo-first-order kinetics and adsorption thermodynamics are better. The adsorption process is a physical adsorption rather than the chemical interation. The adsorption force decreases with the increase of temperature. The obtained PAM / SA composite microspheres have excellent adsorption capacity for dye removal from wastewater.
Carboxymethyl cellulose/polyacrylamide composite hydrogel
The removal of heavy metal ions, e.g. Cu II, Pb II and Cd II, from the wastewater was investigated in terms of the adsorption isotherm and kinetics. As a further demonstration, the adsorbed Cu II ions were in situ reduced within the 3D network, leading to the Cu NPs-loaded CMC/PAM composite hydrogel exhibiting excellent catalytic activity

Recent advances in removal of lignin from paper industry
Shankar et al. (2013) also used Al electrode for lignin removal from synthetic wastewater at pH 7.6 in 75 min. 3.1.2. Adsorption. Nowadays, adsorption technology is more efficiently used for the removal of color and other organic compound from various industries.
2.1. Preparation of the Biosorbents. Morus alba L. fruit peel was obtained from oriental medical college, Gyeongju.The collected biomass was dried in open air and ground in a mill to get fine powder. The peel powder was washed twice with deionizer water and dried at 60°C for 24 hrs then boiled in double distilled deionizer water by changing the water repeatedly until water becomes colorless
Media coverage-.
Stabilization pond is mainly algal-bacterial joint action to remove the pollutants in the wastewater, with construction less investment, low operation cost, simple maintenance, can effectively remove the organic matter and pathogens in the water, and dont need to sludge treatment etc. Germany and France have different kinds of stabilization pond, 3000 and 3000, respectively, while the United
AbstractThe role of polypyrrole-cellulose (PPy-Ce) nanocomposite for the removal of Ni(II) from aqueous solution was investigated by batch experiments. The PPy-Ce nanocomposite was prepared by chemical oxidate polymerization of pyrrole monomer with cellulose. Transmission electron micrography (TEM) showed the size of the particles varied from 80 to 95 nm.

On the other hands, the purity, nature and chemical bonds of different ZnO nanoparticles were also supported by Fourier-Transform Infrared Spectroscopy (FTIR) (Nicolet FT-IR Avatar 360) characterization as shown in Fig. 3.Prominent absorption peaks for commercial ZnO, ZnO-PVP and ZnO-PEG were obtained at the same range at 3000–4000, 2350, 1634 and 620 cm −1 [].
- What is the price of polyacrylamide anionic grade FOB Qingdao?
- The latest price for Polyacrylamide Anionic Grade FOB Qingdao in China for Q4 2025 is USD 1120/MT. Overall, the market dynamics for PAM in the APAC region were influenced by the global reduction in crude oil production, oversupply of products, and weakened demand from key sectors.
