The resource is scarce and demand is growing as China becomes more industrialized and urbanized. The situation is exacerbated by natural and anthropogenic events such as climate change, pollution, exorbitant patterns of water consumption, and an uneven distribution of water resources, with devastating impacts on ecosystems, international relations, food security and public health. In this paper, an overview of China’s water resources is presented. Studies on distribution, consumption patterns and pollution of water resources are reviewed in order to understand the over-exploited and unexplored dimensions of the Chinese water landscape. The status of water resources is also studied with an intention of providing information on the dynamics of water quality and quantity. The paper concludes with a discussion on China’s commitment to rebalancing its water growth model and the measures taken to achieve that.展开更多

This has stimulated studies to develop and adopt novel techniques which consider the removal of pollutants with premium on economic feasibility, simple instrumentation, and high performance. In the treatment of water, the removal of trace concentration organic compounds and other numerous polluted water effluents is difficult due to limited affinity of trace compound ions to ion exchange resins. Because of the selective nature;recognition properties;adsorption ability;high stability;and easier preparation of molecular imprints, they are considered attractive and suitable artificial receptors to be applied in analytical separations, drug delivery, and as chemical sensors. In this review, we touch on the fundamentals of molecularly imprinted technologies and underscore some recent advances made in the development of imprinted polymers that are compatible with water and how they can be used in the clean-up of pollutants.
