The presence of endocrine disruptors in surface waters can have negative implications on wildlife and humans both directly and indirectly. A molecularly imprinted polymer (MIP) was explored for its potential to enhance the UV-Vis determination of trenbolone in water using solid-phase extraction (SPE). The synthesized MIP was studied using Fourier transform infrared spectra (FTIR) and scanning electron microscopy (SEM). Using the MIP resulted in a preconcentration and enrichment factor of 14 and 8, respectively. Trenbolone binding on the MIP was shown to follow a Langmuir adsorption and had a maximum adsorption capacity of 27.5 mg g⁻¹. Interference studies showed that the MIP selectivity was not compromised by interferences in the sample. The MIP could be recycled three times before significant loss in analyte recovery.

分子印迹聚合物（MIPs）作为群勃龙在水中富集吸附剂的探索

地表水中内分泌干扰物的存在可能直接或间接地对野生动植物和人类产生负面影响。探索了一种分子印迹聚合物（MIP）的潜力，可使用固相萃取（SPE）增强水中群勃龙的UV-Vis测定。使用傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）研究了合成的MIP。使用MIP的预浓缩和富集系数分别为14和8。群勃龙在MIP上的结合被证明遵循Langmuir吸附，最大吸附容量为27.5 mg g ^-1。干扰研究表明，样品中的干扰不会损害MIP的选择性。MIP可以循环使用三遍，然后再损失大量的分析物。
