本文提出在盐酸硫胺降解产物存在下,应用复合多项式法Pw=(2p_2-p_3)来消除降解产物对盐酸硫胺吸收光谱的干扰。五份混合物的平均回收率为100.1±0.6%。根据盐酸硫胺(0.0015%m/v)X和降解产物
In this paper, we propose to eliminate the interference of degradation products on the thiamine hydrochloride absorption spectra by using the compound polynomial method Pw = (2p_2-p_3) in the presence of thiamine hydrochloride degradation products. The average recovery of five mixtures was 100.1 ± 0.6%. Thiamine hydrochloride (0.0015% m / v) X and degradation products
