Wastewater from olive oil mills (OMW) represents a major environmental problem that
requires effective treatment to decrease pollution. In the present work, the treatment of olive …

Geopolymers have attracted considerable attention recently due to their promising
environmental and economic benefits. This study used alkali activation to create an …

A new eco-friendly, rapid, and sensitive spectrophotometric method was developed to
determine small quantities of nitrite, based on a diazotization mechanism. In an acidic …

This work investigated cadmium ions biosorption on Fish scales (FS) of Sardina pilchardus.
Different relevant parameters such as initial pH in the range 2.14–7.76, initial cadmium …

Blast-furnace slag-based geopolymers activated by gels siliceous rock (diatomaceous earth)
were synthesized at room temperature. Using a Box Behnken plan and surface response …

The use of geopolymer as a cementitious material for geopolymer concrete (GPC) is
beneficial for the sustainable development and green transformation of the construction …

This work investigated the coagulation-flocculation (CF) process of Reactive Black-5 (RB5)
dye. The individual effects and interactions of different parameters, which include the pH …

The treatment of real textile wastewater by coagulation–flocculation (CF) using ferric
chloride as coagulant and polymer as flocculant was optimized with the central composite …

The chemical synthesis of polysiloxanes from monomeric starting materials involves a series
of hydrolysis, condensation and modification reactions with complex monomeric and …

Sol-gel techniques based on silicon dioxide SiO 2 have been proposed for encapsulation of
organic phase change materials (PCMs), avoiding phase segregation, and enhancing its …
