Abstract-The mineralization of the products of detoxification (neutralization) of yperite3lewisite mixture
by electrochemical oxidation was studied. A procedure for separation of potassium salts and arsenic com-
pounds by electrocoagulation was developed. A possibility of using the resulting potassium salts as fertilizers
for agriculture was discussed.
Russia’s stock of chemical warfare includes nerve
gases (sarin, soman, and VX) and blister gases [ype-
rite, lewisite, yperite3lewisite mixtures (YLMs)]. The
universally adopted concept of their disposal en-
visages two stages. In the first stage, war gases are
neutralized to give reaction masses unsuitable for
further use for military purposes. The second stage
involves combustion or processing of the reaction
mass into a commercial product.
The procedures for chemical detoxification of
blister gases are rather well developed and tested at
pilot plants; they can be used for practical purposes.
It has been found that the detoxification products, ex-
cluding arsenic compounds, belong to compounds of
hazard grade III .
It has been proposed to utilize the reaction masses
by combustion. However, an analysis of the ap-
proaches to the development of processes based on
the combustion of reaction masses showed that their
realization results in the formation of large amounts of
environmentally hazardous wastes . This, in turn,
caused counteraction of environmentalists and the
public. In addition, the combustion of the reaction
masses is highly expensive: the construction cost of
gas-cleaning systems reaches 30% of the total ex-
The aim of this study was to develop a procedure
for enviromentally safe conversion of detoxification
products of YLMs into mineral fertilizers for agricul-
ture and arsenic compounds serving as secondary raw
materials for the reprocessing indusrtry.
As the object of study served a process solution
from detoxification of YLM obtained by its alkaline
treatment in the presence of monoethanolamine.
The process solution from YLM detoxification (so-
called neutralizate) is a turbid brown-green liquid with
The organic components of 300 ml of the YLM
neutralizate were mineralized using a universal labora-
tory pilot setup (Fig. 1).
The electrolyzer parameters were as follows: operat-
ing volume 100 ml, anode (graphite) surface area
, voltage 6 V, and anodic current density
0.01 A cm
. The electrocoagulator parameters were
as follows: operating volume 300 ml, surface area of
aluminum electrodes 1040 cm
, ac current density
0.01 A cm
, and voltage 6 V.
The electrolysis process and the composition and
amount of organic products were monitored by high-
H NMR spectroscopy .
H NMR spectra were recorded on a WP80SY
NMR spectrometer (Bruker, Germany) under the stan-
dard conditions with compensation of
H signals from
State Institute of Organic Synthesis Technology (Shikhany,
Saratov oblast, Russia).
