Polymer Absorption and Flocculation
Clean coal from the Lower Kittanning seam, pure quartz (999% SiO2) from North Carolina and kaolin clay (Standard Airfloated) obtained from the Georgia Kaolin Company were used in these investigations The surface areas of the solids were determined by gas permeametry and by nitrogen adsorption The use of two methods for determining surface area was dictated by the different types of In most cases, polymer adsorption is an essential prerequisite for flocculation and kinetic aspects are very important The rates of polymer adsorption and of reconformation (relaxation) ofAdsorption and Flocculation by Polymers and Polymer Flocculation of fine particles may occur by polymer bridging, charge compensation or neutralisation, polymer particle surface complex formation and depletion flocculation or by a combination of Polymer adsorption: Its correlation with flocculation
Polymer adsorption and its effect on the stability of
The flocculation is some what more effective for higher molecular weights: at equal polymer concentrations the relative absorbance is lower, while the range in cp where flocculation occurs is broader Also a lower degree of hydrolysis of the polymer favors the flocculation (compare Fig 4d and b) In flocculation practice, polymers are known binding to particle surfaces in “loops”, “trains” and “tails”, as shown in Fig 1 Polymer conformation can therefore be tailormade by selectively pinning down portions of the polymer, to control the percentage of loops and trainsAdsorption and flocculation behaviors of Many polymers used for flocculation are natural in origin (proteins, gums, starch, tannins, and alginates), but recently, synthetic polymers have proved successful, and these are often based on polyacrylamide They have a range of molecular weight (about 10 5 –10 6) with fairly well defined degrees of anionic, cationic, or nonionic charactersChapter 7 Flocculation with polymers ScienceDirect
Polymer Adsorption an overview ScienceDirect Topics
The purpose of polymer adsorption is to modify the interaction between the surfaces, which in turn improves the dispersion of particles, flocculation processes, and surface properties It is most commonly measured through the concentration depletion of a solution after being in contact with the surface While polymer adsorption clearly governs flocculation, the effect it has depends on the response monitored [8] Per cent solids settled and settling rate can show quite different trends from supernatant clarity These flocculation properties reflect the different interactions that can occur, in a claypolymer system [10] For instance, settling rate is aCharge Effects in the Adsorption of Polyacrylamides on In the static adsorption, measurement flocculation of the mineral particles by polymer bridging is an important parameter which may affect the adsorption The flocculation is a function of solid–liquid ratio (S/L) Due to aggregation of mineral particles, increasing the S/L ratio for a polymer solution with known concentration decreases the Adsorption polymer on reservoir rock and role of the
