主 题：Total Alkaloid Tobacco Safer Method KSCN KCN
摘 要：In this paper,an analytical method based on a chemical reaction between KSCN and sodium dichloroisocyanurate-dihydrate in a buffer system was applied to quantify the total alkaloid in *** proposed method replaced the No.35 Recommended Method of CORESTA(CRM 35)with the advantage that this method is safer compared to the CRM35 which uses KCN,a highly toxic *** addition,compared to the current national standard method YC/T 468一2013,the buffer solution preparation was optimized to improve the detection *** validation results indicated that the new method met the test requirements,and the results were consistent with the ones obtained from the CORESTA CRM 35 and the YC/T 468一2013 methods.
