Therefore, the development of efficient adsorbents is a crucial step toward sample preparation. This review summarizes and discusses the research advances in extraction materials over recent years. These extraction materials contain inorganic adsorbents, organic adsorbents, and inorganic-organic hybrid ...
research should be characterized by good representation, randomization, and realism (Kish, 1987). Here realism refers to the practical aspects involved with a survey; in particular, realism implies that the sampling plan is implementable in the field and that the cost of the study is under ...
