Effect of temperature and clay addition on the thermal behavior of phosphate sludge

Hybrid carbonaceous adsorbents based on clay and cellulose for cadmium recovery from aqueous solution

“…50 Mohamed et al also came to the same conclusion that dolomite beaks down into CaCO 3 and MgCO 3 . 51 The surface charge of an adsorbent material generally has the strongest effect on its effectiveness. 52 Therefore, the zeta potential was measured under various pH levels in order to determine the surface charge properties of Gh and ca-GH, as shown in Fig.…”

Influence of Sintering Temperature of Kaolin, Slag, and Fly Ash Geopolymers on the Microstructure, Phase Analysis, and Electrical Conductivity

“…Meanwhile, akermanite was produced, as a major crystalline mineral, as a result of the reaction between calcite and free magnesium and silica oxide according to Equation (4) [ 30 ]. 2CaCO 3 + MgO + 2SiO 2 → Ca 2 MgSi 2 O 7 (akermanite) + CO 2 …”

Antimicrobial ceramic foam composite air filter prepared from Moroccan red clay, phosphate sludge waste and biopolymer

“…The major chemical composition of red clay given in weight percentages is the following: SiO 2 (52.79%), Al 2 O 3 (17. 44%), Fe 2 O 3 (5.85%) (Harech et al, 2021). The phosphate sludge is rich in P 2 O 5 (16.83%) and CaO (31.44%).…”

“…The phosphate sludge is rich in P 2 O 5 (16.83%) and CaO (31.44%). It also contains SiO 2 (27.48%), low quantities of Al 2 O 3 (2.41%) and Fe 2 O 3 (0.93%) (Harech et al, 2021).…”
