This study aimed to evaluate the adsorption capacity of an adsorbent obtained using sanky peel for removal phosphate from aqueous solutions. The was conducted in two stages: (1) preparation considering yield, removal, capacity, and textural characteristics; (2) assessment effectiveness as removing phosphates Batch studied solutions containing calcium ions with selected adsorbent. Adsorption kin...

Powder mixtures with a given molar ratio of Ca/P = 1.67 were prepared under mechanical activation conditions from hydroxyapatite powder Ca10(PO4)6(OH)2 and 1M aqueous solution oxalic acid H2C2O4 at Ca10(PO4)6(OH)2/H2C2O4 1:4. The phase composition obtained mixture included brushite (calcium hydrophosphate dihydrate) CaHPO4·2H2O, calcium oxalate monohydrate CaC2O4·H2O in form whewellite weddelli...

This study reports for the first time effect of particle size bioactive glass 46S6 on physico-chemical and mechanical properties carbonated apatite cement (CPC) composed brushite (CaHPO4. H2O) vaterite (CaCO3). Three ranges were investigated: coarse (BGc: 100–200 ?m), medium (BGm: 40–100 fine (BGf<40 ?m). For composite formulations, three liquid phases used: distilled water as a simple setting ...
