1)  adsorbed phosphorus
吸附态磷
1.
The adsorbed phosphorus loss is one of the adverse effects of soil erosion,which results in not only the degradation of soil fertility,but also the deterioration of water environment.
吸附态磷流失是土壤侵蚀的结果之一,不仅造成土壤肥力流失,还是导致水环境恶化的重要因子。
2.

鉴于与吸附态污染负荷有关的流域降雨、土壤、地形、植被、水土保持、泥沙输移比等因素具有空间不确定性的特点,构建了基于盲数理论的非点源吸附态磷污染负荷动态分布模型。
2)  absorbed nitrogen and phosphorus
吸附态氮磷
1.
Estimation of soil erosion and its application in assessment of the absorbed nitrogen and phosphorus load in China;
全国土壤侵蚀量估算及其在吸附态氮磷流失量匡算中的应用
3)  adsorbed nitrogen and phosphorus pollution
吸附态氮磷污染
1.
Employing the non-point source adsorbed nutrition load model,the loads of adsorbed nitrogen and phosphorus pollution were calculated and analyzed.
以美国通用土壤流失方程为基础,根据研究流域的特征和已有的研究成果确定方程中的因子算式,在地理信息系统GIS支持下,估算了各单元的土壤流失量,应用吸附态非点源污染负荷模型,对嘉陵江流域吸附态氮磷污染负荷进行了数值模拟与定量分析。
4)  Adsorbed inorganic phosphorus
吸附态无机磷
5)  phosphate adsorption
磷吸附
1.
The effect of several organic acids on phosphate adsorption in brown red soil and its coating with aluminum hydroxides was studied by isothermal equilibrium method.
结果表明:供试1mmol/L、8mmol/L有机酸都使土壤(原状土或包被土)的磷吸附量降低,同一浓度下,其降低顺序是柠檬酸>草酸>酒石酸>苯甲酸≥乙酸;加入柠檬酸、草酸浓度在1~8mmol/L范围内,土壤吸附磷量随有机酸浓度增高而下降,但包被土的下降幅度较小;加入柠檬酸和草酸浓度为1、4mmol/L,磷浓度为80mg/L时,随有机酸溶液pH升高,土壤吸磷量出现“低→高→低”的变化,原土峰值出现在有机酸溶液pH8~9时,铝包被样峰值出现在起始pH4左右;有机酸先于磷加入到土壤时,对土壤吸磷量的影响比两者同时加入的大,反之则影响最小,加有机酸并离心弃去清液再加磷,土壤吸磷量比加有机酸而不离心的高。
2.
A series of hydrotalcite-like compounds(HTALs) were made by coprecipitation with divalent ions(Mg~(2+),Zn~(2+),Cu~(2+),Ni~(2+) and Co~(2+)) and trivalent ions(Al~(3+) and Fe~(3+))in order to be applied in phosphate adsorption as a new sorbent.

6)  phosphorus sorption
磷吸附
1.

分子式:
CAS号:

性质:在催化剂表面上吸附的分子,通过与表面原子间的吸附键(解离或不解离吸附的共价键或离子键等)构成不同的吸附形态。如CO在W上的吸附态,几何上可有桥式和线式之分,从活化程度来看,又有普通吸附态(即与原分子相比,结构虽有较大变化,还有相当的稳定性)和活化吸附态之分。多相催化中,究竟是什么样的活化吸附态起作用,以及如何产生这样的活化吸附态,从而实现所希望的催化过程,是催化研究的核心问题之一。
