The thermal treatment of the silica-zirconia montmorillonite K10 and silica-ferri oxide montmorillonite K10 nanocomposites at 300 and 500 °C has been carried out, respectively as part of a study of their function as the catalyst. The heating effect on the crystallinity and the lattice parameter calculation of both nanocomposites was studied using XRD and FTIR instruments. The results showed that the nanocomposite silica-zirconia montmorillonite K10 has a thermal resistance and the crystallinity better than the silica-ferri oxide montmorillonite K10, and both have values varying lattice parameters.
作为催化剂功能研究的一部分,对二氧化硅-氧化锆蒙脱土K10和二氧化硅-氧化铁蒙脱土K10纳米复合材料分别在300℃和500℃下进行了热处理。利用XRD和FTIR仪器研究了加热对两种纳米复合材料结晶度的影响和晶格参数的计算。结果表明:纳米复合二氧化硅-氧化锆蒙脱土K10的耐热性和结晶度均优于二氧化硅-氧化铁蒙脱土K10,且两者的晶格参数不同。

Ageratum Conyzoides L. has a toxic and bioactive component as anti-cancer and especially for the root, it has anti-tumor. In order to figure out the active component, it is necessary to do four steps; isolation, identification, characterization, and toxicity essay Brine Shrimp Lethality Test (BSLT) of non-polar fraction Ageratum conyzoides L plant. Isolation method consist of four parts; extraction, partitioning of Kupchan method, fractionation, and purification. Fractionation method uses press column chromatography (KTT). Furthermore, purification process uses thin layer chromatography (TLC) and characterization with spectroscopy FTIR, 1H-NMR and 13C-NMR. Then characterization utilizes spectroscopy FTIR, 1H-NMR and 13C-NMR. The toxicity essay toward Artemia Salina Leach n-hexane fraction and dichloromethane fraction showed that the fraction had toxic properties with number of LC50 are 0,0237 and 4,642 µg/mL respectively. Moreover, n-hexane fraction  has succeed in isolating Stigmasterol compound shaped white crystalline needles with 19.6 mg weight, 143-144 °C melting point and and had toxic properties with number of LC50 are 30,33 µg/mL.
