The present study described a novel application of simple potentiometric enzymic method for anal. of surfactants based on their inhibitory effect on acetylcholinesterase enzyme (AChE). The enzymic activity was measured through monitoring hydrolysis of acetylcholine (ACh) with a disposable acetylcholine potentiometric sensor. Comprehensive investigations were carried out including the effect of incubation time, cholinesterase enzyme and the working calibration ranges. Based on inhibition of AChE, different cationic, anionic and nonionic surfactants were determined in the concentration range from 0 to 40 μg mL-1 with detection limits reaching 0.07 μg mL-1 depending on the nature of surfactants. The degree of AChE inhibition caused by different tested surfactants were as follows: cetylpyridinium chloride (CPC)>benzyldimethylhexadecyl ammonium chloride (BDHAC)>Hyamine (Hy)>cetyltrimethylammonium bromide (CTAB)>Triton X-100 (TX-100)>sodium dodecyl sulfate (SDS). The proposed method was applied for determination of surfactants in pharmaceutical formulation, detergents products and environmental samples with acceptable sensitivity and reproducibility. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Category: chlorides-buliding-blocks).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Category: chlorides-buliding-blocks
