誰能幫幫我幫我翻譯一下這一段英文 不要用翻譯軟體

10 microlitre aliquots

of solution were removed and added to solutions containing

15 ml of distilled water and 1.5 ml of an acidic solution containing

ammonium molydate and the resulting solution

allowed to stand for 15 min, thereby allowing any dimers

present to decompose to monomers which could be detected by

the colorimetric method. 8 ml of a reducing solution containing

Metol was then added and the absorbance of the blue

silicomolybdate complex measured after 2 hours at 810 nm

using a Unicam UV2 UV-VIS spectrometer. Calibration of this

method using a standard silicate solution [BDH] showed a

linear relationship between concentration and absorbance over

the whole of the concentration range used (0–35 mmol dm23)

and an experimental error in measurement of ¡1.0%.

Orthosilicic acid concentrations were measured at intervals

between 0.5 and 240 min after the initial pH reduction with

20–30 measurements being taken within the first hour. The

equilibrium orthosilicic acid concentration (for an individual

system) was reached within 2 hours reaction. Readings were

continued for the first 24 hours of reaction with the precipitated

silica being removed after 168 hours of reaction, washed three

times with distilled water to remove traces of catechol and

other solution species, centrifuged at 8000 rpm, rapidly frozen

in liquid nitrogen and freeze-dried at 223 K using a Christ

alpha 1–4 freeze-dryer.

    這.....

    是實驗的流程吧

    我只看的懂一半, 因為很多都是專有名詞

    (我不是讀科學的 所以沒辦法幫你全部翻出來 @@")
