The pretreatment condition of sample, chemical interference, identity of viscosity for test solution and its blank solution, background absorption interference and detection limit were all studied.
对样品处理条件、化学干扰、试液粘度与空白溶液粘度的一致性、背景吸收干扰及检出限进行了考察。
By the blank experiment, the standard comparison and the test of the standard sample, some better results are gained.
另外利用改进后的方法针对标准样品进行了测试试验，验证了改进方法的准确性和可靠性。
