The P adsorption capacity gradually decreased with increasing particle size, and the contributions from kaolin and montmorillonite to P adsorption were significant despite representing only a …

The aim of this study is to investigate the capability and mechanism of phosphorus adsorption present in water through thermally treated kaolin. For this purpose, batch experiments are conducted to treat synthetic water samples with phosphate content using kaolin sourced from the northern region of Albania. The kinetics and mechanism of adsorption are examined.

Kaolin and phosphate rocks are relatively rare in the world geological environment, a fact of which increases geoheritage value of their occurrence in Egypt. Additionally, aesthetic properties of kaolin (white colour – Fig. 2) make it attractive to possible visitors, which also contribute to geoheritage value.

cannot be dumped in landfill due to the metal content. Valorisation of the waste will be beneficial in a way that it conserves natural reserves and reduces energy consumption. ...

The key characteristics of the kaolin samples include mineralogy, the degree of kaolin crystallinity, chemistry, morphology, particle size, size distribution, shape and shape distribution, surface chemistry, interfacial …

Phosphorus (P) has been largely applied in many industries, which inevitably produced industrial wastewater containing both inorganic and organic P, such as circulating cooling water, membrane concentrate, and textile wastewater [1], [2], [3].

The result reveals that both kaolin and phosphate rocks contain valuable elements essential for bone metabolism such as Sr, Zn, Cu, Mn, Ba, Cr, and V. ... reducing the kaolin content led to a slight decrease in the SiO 2 and Al 2 O 3 contents. It also found that the TiO 2 content in the batches was decreased by decreasing the kaolin content.

The beneficial effect of kaolin spray on phosphorus content could partly be attributed to the increased growth as well as to gas exchange, thus enhancing nutrient uptake under stress conditions (Hu and Schmidhalter 2005). Conclusions.

The latter interaction is perhaps the most interesting treatment effect and is clearly demonstrated by the data of Table 5. The M.E. content of diets containing phosphorus source 1 increased as the phosphorus content increased whereas increasing the levels of phosphorus sources 2 and 3 tended to depress M.E. values.

The invention discloses a preparation method of a lanthanum-modified kaolin phosphorus removal agent, which comprises the following steps: adding LaCl 3 Adding the solution into kaolin, stirring for the first time to form a mixed solution A, adding NaOH into the mixed solution A, stirring for the second time to form a mixed solution B, continuously adding an alkaline solution, stirring for …

Mullite with an aspect ratio of 82.08 was prepared by adding 4.5 wt% Ca 3 (PO 4) 2 to citric acid activated kaolin. Phosphorus (P) has a significant role in the formation of well-developed mullite whiskers. The mechanisms were discussed based on X-ray diffraction, FTIR, SEM, EDS and 31 P MAS NMR. The addition of P decreases the quartz content, but increases …

In this study, the novel kaolin/lanthanum carbonate (KLC) composites were prepared for the simultaneous sorption of phosphate and phosphonate, and their surface morphology and crystal structure were characterized. The sorption kinetics and isotherms results indicated the competitive sorption of orthophosphate and phosphonate on the surface of KLC.

The direct effects of dissolved organic matter (DOM) on the sorption of orthophosphate onto gibbsite, goethite, and kaolin were examined using a one-point …

The current study demonstrates the possibility of producing novel economic biomaterials with biocompatible and acceptable mechanical properties for bone tissue engineering applications from dolomitic phosphate and kaolin rocks. The solid-state reaction was adapted to produce various batch compositions, through the substitution of kaolin with dolomitic …

As can be seen from Table 2, the PAC product prepared with kaolin is slightly superior to the commercial PAC in coagulation performance. 5. Treatment of High Concentration Phosphorus Containing Wastewater by Polyaluminium Chloride Through the detection of the sample water, we f ound that the total phosphorus content was 40mg/L, and

Among various strategies for mitigating harmful algal blooms (HABs), coagulation–flocculation of algal cells by modified clay (MC) has proven to be an effective method that is widely applied in East Asia. Inorganic nutrients produced by algal detritus decomposition after an HAB are quickly released into the overlying water, which may cause second eutrophication. For environmental …

Saturated solution of 2˛g DAhP was added to the kaolin suspension and stirred overnight on magnetic stirrer at room temperature for proper interaction of DAhP with kaolin. The suspension was then soni-cated, and the supernatant liquid obtained was kept to check any loss of phosphate. The
