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
Xu et al. (2014) carried out a study using polyacrylamide functionalized graphene using 纬-ray irradiation for Pb(II) removal, and demonstrated an adsorption capacity of 819.67 mg/g. However, there exist few studies regarding the heavy metal removal of the lower cost dual flocculant.

The adsorption isotherms of PMG on goethite and magnetite conformed satisfactorily with the Langmuir model (R 2 > 0.990, Fig. 2a). The maximum adsorption capacity (q e) was 7.9 mg/g for goethite and 6.7 mg/g for magnetite at pH = 7, respectively.Additionally, PMG can also be adsorbed by MnO x Al 2 O 3 (with 81% removal rate at pH = 3) and TiO 2 (with 74% removal rate at pH = 3; or with a

polyacrylamide emulsions and powders Handling of emulsions using pumps is simpler than powders and in many cases, in-line injection can be used, avoiding the need for an aging tank. Furthermore, dissolution times are much shorter and there are almost no solubility problems. Unlike powders, emulsions are complex multicomponent products which include
Muscovite/phillipsitic zeolite was introduced as a novel inorganic composite of stunning adsorption properties. The composite was investigated in the uptake reactions of Hg(II), As(V), and U(VI) as highly toxic water contaminants considering different adsorption factors. The adsorption properties of muscovite/phillipsitic zeolite are highly dependent on the pH values and the best

Poly(2-(dimethylamino)ethyl methacrylate)-grafted bentonite, marked as Bent-PDMAEMA, was designed and prepared by a surface-initiated atom transfer radical polymerization method for the first time in this study. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA) were applied to characterize the

Equilibrium and Thermodynamic Studies on the Adsorption
Removal of tartrazine by an agricultural waste, coconut husks (CH), was investigated and compared with activated carbon (AC). The effect of pH, temperature, amount of adsorbent, contact time, initial dye concentration, and particle size on the extent of adsorption by the two adsorbents was investigated. The maximum adsorption capacity was obtained for pH 2.5, adsorbent dose of 3.3 g路L鈭?

A Review of Gemini Surfactants: Potential Application
Gemini surfactants are a group of novel surfactants with more than one hydrophilic head group and hydrophobic tail group linked by a spacer at or near the head groups. Unique properties of gemini surfactants, such as low critical micelle concentration, good water solubility, unusual micelle structures and aggregation behavior, high efficiency in reducing oil/water interfacial tension, and
