The objective of the present work was to determine the effect of two fuel additive sorbents, i.e. kaolin and calcite (CaCO3) on the aerosol particle emission and characteristics during combustion of pelletized woody biomass fuels, i.e. bark and cleaning assortments in a residential pellet burner. The influence of adding 1 2 wt % of the additives to woody …

Here we use the incorporation of sulfonated fluorescent dyes to gain new understanding of additive occlusion in calcite (CaCO 3), and to link morphological changes to occlusion mechanisms. We demonstrate that these additives are incorporated within specific zones, as defined by the growth conditions, and show how occlusion can govern …

It is proposed that the different anisotropic dissolution behaviors of calcite are strongly related to the concentrations and the adsorption features of the additives on the calcite surface. Similar to the crystal growth process, additives have a strong influence on the dissolution process of crystals. Studies on the dissolution process may shed light …

While calcite media can typically increase the pH of water by 1, magnesium oxide and corosex used together can increase pH by up to 1.5. When using calcite and corosex together, you should be adding roughly 10%-20% magnesium oxide and 80%-90% calcite media. ️ Be wary of adding too much corosex, as it may raise the pH of the …

Many studies have evaluated the effects of aqueous constituents on calcite growth and dissolution, with the greater focus on inorganic ions. Both inhibition (e.g., organic acids, Fe2+, Mg2+, Sr2+, PO43−) and enhancement (e.g. chelators, Cl−, I−, F−,) of dissolution kinetics have been observed [33–42], and in some cases enhancement …

After 24 h, the amount of calcite reacted was 78.4% at pH 3 with 10.8 ± 1.0 ppm fluoride remaining, and it was 24.0% at pH 7 with 38.0 ± 1.8 ppm fluoride remaining.This showed that the kinetics of the fluoride uptake was much faster at pH 3, and it could be attributed to the higher solubility of calcite at lower pH [15], [28].Also, note …

The salt form of phytic acid is called phytate, and almost all phytic acid (Figure 19.1) is present as a mixed salt (phytin). Phytate P is poorly available to monogastric animals due to the lack of endogenous enzymes and can reduce the digestibility of other nutrients, affecting growth and performance.
