Alkali Fusion(碱熔)研究综述
Alkali Fusion 碱熔 - The molar ratios of SiO2/Al2O3 and Na2O/SiO2 were tuned before alkali fusion by adding different amounts of Al(OH)3 to the fly ash along with the alkali agent, Na2CO3. [1] In this research ZrO 2 has been synthesized from Kereng Pangi zircon sand in Central Kalimantan through alkali fusion-coprecipitation method. [2] Alkali fusion of ferronickel slag using Na2CO3 in the roasting process was carried out. [3] The specific objective is to determine the optimum conditions of magnesium extraction in the process of alkali fusion followed by hydrochloric acid leaching. [4] The initial sample is ferronickel slag which had been proceed by alkali fusion by adding 20 wt. [5] Herein, low alumina fly ash (LAFA) was utilized to fabricate the As(V) and As(III) adsorbent via combining the routes of alkali fusion and incipient-wetness impregnation. [6] In contrast, alkali fusion at 600 °C for 4 h activated the majority of aluminium species and 3 was required if zeolite W was to be synthesized rather than zeolite L. [7] The aluminosilicate supernatant from the alkali fusion of LCDwg and CMPs and the surfactant cationic cetyltrimethylammonium bromide (CTAB) were used as structure-directing agents. [8] The influence of alkali fusion and acid leaching treatment on microstructures and physicochemical properties of iron ore tailings is investigated in detail. [9] In this study, a series of X-type zeolite molecular sieve catalysts, modified with copper (Cu-X), were prepared by an alkali fusion–hydrothermal synthesis using coal gangue from Inner Mongolia. [10] Additionally, an alkali fusion for major element analysis was applied and tested. [11] Alkali fusion of iridium was successfully performed using a vertical beam irradiation method and a mixed target of Ir and Na2O2, which resulted in easy dissolution of the irradiated iridium target. [12] Alkali fusion of the acid-extracted samples produced GIS-type zeolite. [13] Furthermore, polymorph zirconia (ZrO2 – amorphous, tetragonal, and monoclinic) and silica (SiO2 – amorphous and cristobalite) nanopowders were also successfully derived from the purified zircon powder using a bottom-up method via alkali fusion and co-precipitation processes followed by calcination. [14] We used alkali fusion and hydrothermal procedure to prepare the nanostructured adsorbent, BR zeolite-4A, which was characterized with field emission scanning electron microscopy, X-ray diffraction, and carbon dioxide adsorption apparatus. [15] Traditional hydrothermal method (TH) and alkali fusion-assisted hydrothermal method (AFH) were evaluated for the preparation of zeolites from waste basalt powder by using NaOH as the activation reagent in this study. [16] In this work, we prepared basalt based nanostructured zeolite 13X by alkali fusion and hydrothermal synthesis process. [17] The extraction of silica was carried out under several extraction methods (alkali fusion (AF), reflux (RF) and microwave heating (MW)) and extraction parameters (NaOH/RHA mass ratio, fusion temperature and H 2 O/NaOH-fused RHA mass ratio). [18] A supernatant solution of the silicate species extracted after alkali fusion of the acid-treated power plant fly ash was used to prepare mesoporous silica foams (MSFS) in acidic condition, where Pluronic P123 and trimethylbenzene (TMB) were used as the structure directing agent and swelling agent, respectively. [19] A low-cost and simple method was proposed to synthesize SiO2–Al2O3 composite aerogel from fly ash by alkali fusion-acid leaching-ambient pressure drying process just in 3 days for the first time. [20] Na-X zeolite and NaP1 zeolite with hierarchical pores were synthesized through alkali fusion with hydrothermal at 100 oC for 24 hours. [21] The preparation of zeolite A from high alumina fly ash (HAFA) of China has been carried out using the alkali fusion and hydrothermal synthesis method with the consideration of comprehensive utilization of the alumina and silica contents in HAFA. [22] This review focuses on the recent advances in sample digestion methods, especially on open-vessel acid digestion, high-pressure acid digestion, microwave digestion, alkali fusion, high-pressure asher, and sample preparation methods for laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis. [23] In this paper, a two-stage hydrometallurgical process (alkali fusion-acid leaching) was developed to recover REEs from CFA.
