Electrodialysis Processing of Deactivated Vat Residues of NPP

A study of the possibility of using Electrodialysis for the simultaneous separation of multicomponent solution of deactivated vat residues of the ion-selective cleaning plant (ISCP) NPP for three chemical reagents is presented. A prototype of chemical component recycling plant with a capacity of 5 liters per hour was designed and built. Studies have been carried out confirming the possibility of obtaining acid and alkali from deactivated vat residues (VR) of NPP using Electrodialysis. It is proposed use results of work when developing a compact pilot plant for processing of deactivated vat residues of NPP with WWER. The use of Electrodialysis to separate of multicomponent deactivated solution VR ISCP NPP allow effectively remove boron components for reuse.

STAGED PREPARATION OF DEEP BURNS TO AUTODERMOPLASTIKS AFTER NECROTOMY

Summary. A method was developed and used under clinical conditions for the stepwise preparation of deep burns for autodermoplasty after necrectomy in 57 patients with thermal injury. The method consisted in the application of neutral wound dressings, dressings and irrigation regimen developed complex multicomponent solution at the stages of treatment. A positive effect of the proposed treatment on the course of the wound healing process and improvement of the main clinical indicators of treatment was established.

Microscopic fungi sorption of chemical elements from multicomponent solution

The data of micromycetes species and strain specificity in the process of toxic elements extracting from multicomponent solutions were obtained as results of modal experiments. The results also indicate the capability of biogenic mineral formation in organic strata.

A method for estimating the certified value uncertainty of a multicomponent reference material

This paper presents the results of a series of studies aimed at investigating the reference material (RM) of a multicomponent solution. An algorithm for estimating the uncertainty induced by the chemical element content in the RM is proposed taking into account the mass of the measurand in each component of the mixture. The results calculated according to the preparation procedure using the proposed algorithm were confirmed by the Monte Carlo method, while the elemental content in the mixture was confirmed via inductively coupled plasma optical emission spectroscopy. The applicability of weighted mean estimates for characterizing an RM of a multicomponent solution is shown.
