求助一段英文翻译。汉译英。

巯基棉分离富集-分光光度法测定矿石中的微量金
本文研究了在表面活性剂Tween-80存在条件下，用硫代米嗤酮（TMK）作显色剂、巯基棉分离富集分光光度法测定矿石中的痕量金。在25mL显色体系中，各试剂的最佳用量是：TMK（0.05%乙醇溶液）1mL；HAc-NaAc缓冲液最佳pH值为3.2，最佳缓冲液用量是3mL；表面活性剂Tween-80（5%水溶液）最佳用量是1.5mL。金与TMK形成的配合物的最大吸收波长为550nm，配合物的配位比为Au：TMK=1：1。金含量在0～12.875μg/25mL内符合郎伯-比尔定律。回收率达到，RSD为。该方法具有灵敏度高，准确度好，操作简便，快速的特点，该方法可广泛应用于矿石中金的快速准确的测定。
感谢大家的帮忙。但是请最好不要直接弄到翻译工具里面让它自己翻译。那样翻译出来的都是中国式英语。。。

Sulfhydryl cotton preconcentration separation - Determination of trace gold in ore
In this paper, the surfactant Tween-80 the existence of conditions, one with S-meter deride (TMK) as color reagent, sulfhydryl cotton Spectrophotometric Determination of separation and preconcentration of trace gold in ore. 25mL color in the system, the amount of the reagent is the best: TMK (0.05% ethanol solution) 1mL; HAc-NaAc buffer pH value of 3.2 the best, the best is the amount of buffer solution 3mL; surfactant Tween-80 (5% aqueous solution) is the best dosage of 1.5mL. TMK gold with the formation of complexes of maximum absorption wavelength of 550nm, the coordination complex than for the Au: TMK = 1:1. Gold content in the 0 ~ 12.875μg/25mL to satisfy the Lambert - Beer's law. Achieve recovery, RSD for. The method has high sensitivity, good accuracy, easy to operate, the characteristics of fast, this method can be widely used in gold ore in the determination of fast and accurate.
