Determination of Trace Extractable Lead in Artificial Acid Sweat from Ecological Textiles by GFAAS
Chong-hua LIU, Han FANG, Xiao-yang LIN, Xiao-li ZHANG, Zhi-guang DENG, and Yun-song LI
Extractable trace level lead in artificial sweat solution from ecological textiles is a key item limited by eco-textile standard. But the content of this extractable Pb is not so easy to determine for the strict limit of eco-textile standard, the complicatedness of extractable solution matrix and the strong background

Adsorption Characteristics and Mechanism of 2,4-D on Two Types of Humic Acid
Chun-ying CHANG, and Yi-zhong LV
This study mainly focused on the adsorption properties and adsorption mechanism of 2,4-D on two different humic acids. After the extraction of humic acid from the two different types of soil, the black soil and chestnut soil, adsorption experiments were carried out using the batch equilibrium techniques. Then FTIR and

Purity Measurement of Hybrid Rice Seed Yixiang 725 with Visible-Near Infrared Reflectance Spectra
Liang LIANG, Min-hua YANG, Zhi-xiao LIU, Hai-wei XU, Fu-hui LIU, Qi-zhuang HE, and Yun-fei LUO
A rapid and non-invasive method was put forward to measure the purity of hybrid rice seed by visible-near infrared reflectance spectra. Ninety hybrid rice seed samples (Yixiang 725) with the purity of 90%-99% were collected using a FieldSpec3 visible-near infrared spectometer. All samples were divided randomly into tw
