Interaction forces between goethite and polymeric flocculants and their effect on the flocculation of fine goethite particles

TL;DR: In this article, the utilization of various types of natural and modified polymers for removing toxicant dyes in wastewater generated by the dye industry is reviewed in a survey of 80 recently published papers.

TL;DR: In this article, the surface properties of minerals at the solid/water interface and their surface interaction mechanisms with other objects in complex aqueous media at the nanoscale has been established.

TL;DR: In this paper, the effect of clay mineral surface chemistry on settling, flocculation, and dewatering using pure clay samples and coal tailings samples was systematically investigated and shown that the importance of clay surface chemistry in controlling clay interactions with chemical reagents, and solid-liquid separation to dewater the clay-rich tailings inherently present in the mining industry.

TL;DR: In this paper, S-[(2-hydroxyamino)-2-oxoethyl]-N,N-dipropyl dithiocarbamate (HAPTC) was firstly developed for the flotation separation of galena and sphalerite.

TL;DR: In this article, the authors used the atomic force microscope to measure the forces between a planar surface and an individual colloid particle, a silica sphere of radius 3.5 µm, attached to the force sensor in the microscope and measured in solutions of sodium chloride.

TL;DR: An alternative interpretation of why hydrophilic surfaces and macromolecules remain well separated in water is suggested, in which hydration forces are either attractive or oscillatory, and where repulsions have a totally different origin.

TL;DR: In this article, a review examines physico-chemical requirements necessary to achieve stimuli-responsiveness in heterogeneous polymer networks as well as discusses recent developments and future trends while individual structural components of polymeric networks are responsible for localized chainresponsiveness, desirable spatial and energetic network properties are necessary for collective and orchestrated responsiveness to external or internal stimuli.

TL;DR: In the presence of high concentrations (> 3 M) of divalent cations, where the electrostatic force can be completely ignored, another repulsive force was observed with silicon nitride tips on mica and this repulsion is attributed to the hydration force.
