【摘要】：以Ti Cl_4為原料,采用沉淀法制備出均一粒徑的Ti O_2微球。利用XRD、SEM、TG,反射光譜儀對Ti O_2微球進(jìn)行了結(jié)構(gòu)表征與性能測試�？疾炝四蛩赜昧俊⑷軇┓N類和用量、Ti Cl_4濃度、羥丙基纖維素(HPC)質(zhì)量濃度和合成時間對制備Ti O_2微球的影響。Ti O_2微球的最佳合成條件為:c(Ti Cl_4)=0.2 mol/L,V(水)∶V(正丙醇)=1∶3,n(尿素)∶n(Ti Cl_4)=6∶1,HPC的質(zhì)量濃度為0.85 g/L,90℃下反應(yīng)80 min,焙燒溫度為500℃。在此條件下,Ti O_2微球產(chǎn)率87.9%,其粒徑可達(dá)2~3μm。以該Ti O_2微球制備干化學(xué)體外診斷試劑的反射、擴(kuò)散雙功能層,結(jié)果表明:在400~780 nm可見光范圍內(nèi),雙功能層的光反射率達(dá)90.7%以上。血清經(jīng)雙功能層擴(kuò)散至試劑層,反應(yīng)后形成的斑點(diǎn)顏色均一,表明血清經(jīng)此雙功能層擴(kuò)散均勻且重復(fù)性好。
[Abstract]:TIO _ 2 microspheres with uniform particle size were prepared by precipitation method using Ti Cl_4 as raw material. The structure and properties of TIO _ 2 microspheres were characterized by means of XRD-SEMM-TG and reflectance spectrometer. The amount of urea, the type and amount of solvents and the concentration of Ti Cl_4 were investigated. Effect of concentration and Synthesis time of hydroxypropyl Cellulose on the preparation of TIO _ 2 Microspheres. The optimum synthesis conditions of TIO _ 2 microspheres are as follows: Cl_4)=0.2 / L / V (water: 1: 3). The mass concentration of TIO _ 2 microspheres is 0.85 g / L ~ (-1) for 80 min at 0.85 g / L ~ (-1) 鈩，
