Interactions of polyacrylamide polymer with bentonite
Interactions of polyacrylamide polymer with bentonite in aqueous systems Article in Materials Letters 48(3-4):168-175 · April 2001 with 258 Reads How we measure 'reads'
Anionic Polyacrylamide go4WorldBusiness. Anionic polyacrylamide Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.
Efficiency of Egyptian drilling muds in the presence
The flow properties of Egyptian bentonite were studied using a combination of anionic polyacrylamide (MW = 1,000,000 g mol−1) and cationic polyethylene imine (MW = 700,000 g mol−1).
Keywords: Bentonite, superabsorbent polymers, nanocomposite, microwave synthesis, clay based composite material. Introduction: Preparing clay based superabsorbent polymer composite is gaining importance day after day due to enhanced properties and lowering cost of the resulting composite compared with the cost of pure polymer [1].
Effect of electrolytes on electrokinetics and flocculation
To assess the effect of electrolytes on flocculation, bentonite dispersions were prepared in 1 L salt solutions of concentrations 0.001, 0.01 and 0.1 mol/L for NaCl, CaCl 2, MgCl 2.6H 2 O and KCl in deionized water. 1.5 g/L of bentonite was homogenized in the salt solution for 3 min. Bentonite-polyacrylamide dispersions were then prepared at
The effect of silica nanoparticle size and concentration on the mechanical strength and wellbore plugging performance of SPAM/ chromium (III) acetate nanocomposite gels was investigated. First
REVIEW OF CLAY-DRUG HYBRID MATERIALS FOR BIOMEDICAL
The kaolin group of minerals, including kaolinite (Kln) and halloysite, has a 1:1 layer-type structure, in which the layer is composed of a tetrahedral silica sheet and an octahedral alumina sheet combined in a unit, and the layers are stacked along the c axis by hydrogen bonding interaction. Although Kln also has a relatively small specific surface area (SSA) compared to other types of clay
Oil/water (O/W) emulsion stabilized by surfactants is the part of oily wastewater that is most difficult to handle. Ceramic membrane ultrafiltration presently is an ideal process to treat O/W emulsions. However, little is known about the fouling mechanism of the ceramic membrane during O/W emulsion treatment. This paper investigated how stabilization surfactants of O/W emulsions influence the

- What is poly aluminum-ferric chloride (PAFC)?
- Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
