The role of surfactants (wetting agents) in effective and efficient flotation separation of naturally hydrophobic plastics, such as polyvinyl chloride (PVC) and polyacetal (POM) has been investigated in terms of wettability ...

In the present study the effects of organic additives like triethylbenzylammonium chloride (TEBACL), cetyltrimethylammonium bromide (CTABr) and tetrabutylammonium bromide (TBABr) on zinc electrowinning from acidic sulphate ...

Activation energies and the reaction kinetics for La(OH)(3) and La1-xGdx(OH)(3) powders synthesized by coprecipitation technique have been calculated from the differential thermal analysis patterns and compensation effect ...

The ability of treated alum sludge to remove fluoride from aqueous solution has been investigated. The studies were carried out as functions of contact time, concentration of adsorbent and adsorbate, temperature, pH, and ...

Adsorption of phosphate (PO43-) from aqueous solution on activated red mud (ARM) was studied as a function of time, pH, temperature, concentration of adsorbent and adsorbate in acetic acid-sodium acetate buffer medium. The ...
