苦咖啡酸蘋(píng)果金蟲(chóng) (小有名氣)

[求助]
幫忙翻譯一下實(shí)驗(yàn)步驟
|

All the reactions were carried out at room temperature under ambient conditions. High-purity bismuth nitrate [Bi(NO3)3·5H2O], ferric nitrate [Fe(NO3)3·9H2O], and scandiumoxide [Sc2O3] were o btained from commercial sources(Aldrich). In a typical procedure, an aqueous solution of Bi(NO3)3·6H2O (2.082 g, 4.29 mmol) and Fe(NO3)3.9H2O(1.734 g, 4.29 mmol) was sonicated for 20 min. The pH of the solution was then adjusted to 8 by adding ammonia solution, and the resultant mixture was irradiated with a high-intensity(100 W cm−2) ultrasonic radiation operating at 20 kHz, under air at room temperature for 100 min. This was done by the direct immersion of a titanium horn (13 mm diameter) to a depth of 6 cm in the solution. The subsequently formed white precipitate was centrifuged and washed with distilled water and finally with acetone. The product was heated under air in furnace at 525 ° C for 1 h. 這是一篇文獻(xiàn)的實(shí)驗(yàn)部分，有幾個(gè)地方不太明確希望大俠給解答一下。 1. sonicated for 20 min 聲處理？是超聲？還是別的社么步驟。 2. irradiated with a high-intensity(100 W cm−2) ultrasonic radiation operating at 20 kHz 這句也不太明白。 3.titanium horn是什么東西？ |
