Selection criteria of xenobiotic leaching models in soil

European Journal of Agronomy, 1995
Selection criteria of xenobiotic dissipation models in soil are discussed. Model potentialities and user requirements are diverse ; it is paramount to evaluate each model in view of its application. Three main topics are evaluated : user/programme interactions, model purposes, and real world/model relationships. 1) A programme (or a paper-written model)

Selective leaching of vanadium from vanadium-chromium slag using sodium bicarbonate solution and subsequent in-situ preparation of flower-like VS2

, 2020
A novel leaching method for selectively separating vanadium from calcification roasted vanadium‑chromium slag (V Cr slag) was proposed, using sodium bicarbonate (NaHCO3) as the leaching medium.

Leaching and recovery of phosphate and rare earth elements from an iron-rich fluorapatite concentrate: Part II: Selective leaching of calcium and phosphate and acid baking of the residue

Hydrometallurgy, 2019
Apatite concentrate is an important source of phosphate and contains significant amounts of rare earth elements (REEs). In this study, the possibility of selective phosphoric acid leaching of phosphate and calcium from the Esfordi (Yazd province, Iran ...

Stable cluster head selection in LEACH protocol

Proceedings of the 7th ACM India Computing Conference, 2014
Optimal cluster head count plays a key role in determining the efficiency of a cluster based routing protocol. If the cluster head count will be more than the optimal value, aggregation advantage cannot be taken fully. If clusters are less, then there will be more aggregation load on the cluster head and communication load on the cluster members as ...

Recovery of zinc and manganese from spent zinc-carbon and alkaline battery mixtures via selective leaching and crystallization processes

Journal of Environmental Chemical Engineering, 2019
A hydrometallurgical process is proposed for zinc and manganese recycling from waste zinc-carbon and alkaline battery mixtures as sulfate salts. The collected scrap battery mixture is crushed, sieved, magnetically separated and ground using industrial ...
