All chemical reagents used in this study such as common metal chlorides, 1,3,5-triformylphloroglucinol (Tp), and p -phenylenediamine (Pa-1) were directly purchased from Kanto Chemical Co., Inc. or FUJIFILM Wako Pure Chemical Corporation and were of analytic grade. A 50 mM of stock solution of Pd(II) were prepared by dissolving the powder in a 2 M hydrochloric acid and then diluting the solution to the required concentration using deionized water. Subsequently, 0.05 g of TpPa-1 was weighed in a 9 mL vial bottle with a screw cap and 3 mL of the prepared working solution was added. The mixture was mechanically stirred at 298 K for an exact time interval. Phase separation was conducted by using a plastic syringe and nylon net filter (20–40 µm pores). The concentration of the tested metal ions before and after adsorption were determined using an inductively coupled plasma atomic emission spectrometer (ICP-AES, Shimazu ICPS-7510). The uptake percentage ( R , Abstract In this study, a hydrochloric acid-stable 2D covalent organic framework (TpPa-1) was prepared. And its adsorption behaviors in the recovery of palladium (Pd(II)) from hydrochloric acid solution was systematically investigated under the effect of contact time, hydrochloric acid concentration, chloride ions concentration, and adsorption capacity. The adsorbed species on TpPa-1 was clarified as chloridated Pd(II) by X-ray photoelectron spectroscopy.","PeriodicalId":16331,"journal":{"name":"Journal of ion exchange","volume":"102 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90201843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since Sr was adsorbed on the granular potassium dititanate by ion-exchange, Sr was leached into acidic solutions or solutions with high cation concentration. The influence of the cationic species in the solution on Sr leachability was larger for Ca than for Na. It can be seen the ion selectivity of potassium dititanate is higher for alkaline earth metals such as Ca and Sr than for alkali metals such as Na and K. Heat treatment was effective in reducing Sr leaching from the simulated spent adsorbent. The heat treatment at 500°C was not effective enough to reduce the Sr leaching, but the heat treatment above 900°C showed a significant reduction in the Sr leaching ratio. This might be related to the stabilization of Sr as Sr 2 Ti O 13 crystal and the reduction of specific surface area of the simulated spent adsorbent. At the heat treatment temperature of 1100°C, there was no significant difference in the crystal phase formed from that at 900°C. However, the specific surface area of the simulated spent adsorbent was reduced, therefore the effect of reducing Sr leaching was even larger.","PeriodicalId":16331,"journal":{"name":"Journal of ion exchange","volume":"434 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91488375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extraction behaviors of major elements (Si, Al, Ca and Mg) from the ash into hydrochloric acid (1 mol/L HCl) and sulfuric acid (0.5 mol/L H2SO4) aqueous solutions were almost same except Ca due to the formation of gypsum in the H2SO4 solution. The ashes leached with 1 mol/L HCl and 0.5 mol/L H2SO4 aqueous solutions were converted into zeolite-P and tobermorite, respectively, while the raw ash was converted into hydroxysodalite. The cation exchange capacities of the converted products from the ashes leached with HCl and H2SO4 were 1.30 and 0.75 mmol/g, respectively, which were higher than that of the product from the raw ash (0.60 mmol/g).

Catalytically active species in interlayer are stabilized by the strong electrostatic interaction between the NiZn host and the guest anion. Furthermore, Brønsted basic anions such as PO 43− or OH − were also able to be integrated into NiZn interlayer. These “intercalation catalysts” promote various liquid phase reactions more effectively. The CuO-CuAl 2 O 4 nanocomposite synthesized by high temperature calcination (1073 K) of Cu-Al layered double hydroxide (CuAl LDH) acted as an effective heterogeneous catalyst for selective hydrogenation of carbonyl compounds with formic acid as a hydrogen donor and acceptorless dehydrogenation of various alcohols.
