Abstract—New cross-linked copolymers based on N-vinylpyrrolidone and N-vinylcaprolactam were proposed for
preconcentration of carbaryl and naphthols from aqueous media. The inﬂ uence of pH, nature of salting-out agent,
surfactant, and temperature on the recovery of the analytes was examined. The most efﬁ cient sorption systems
for recovery of carbaryl and naphthols from aqueous solutions were developed.
Due to high toxicity and mutagenicity of carbamate
pesticides (carbaryl, CL) and their metabolites, the recov-
ery of microamounts of these compounds from aqueous
media, soil, and foodstuff constitutes a main challenge
facing modern applied chemistry. The major source of
contamination of water bodies with carbaryl is uncon-
trolled agricultural runoff of snowmelt, rainwater, and
groundwater. In water, carbaryl degrades to 1-naphthol
Even trace levels of carbaryl are unacceptable for
vegetable products and soils . After biodegradation
of carbaryl, biological media contain microamounts of
1-naphthol. Reliable determination requires preliminary
recovery and concentration of carbaryl and its metabolite
from the aqueous matrix.
Various methods are currently employed for recovery
and preconcentration of organic compounds; in particular,
sorption with the use of carbons, mineral sorbents, and
biosorbents is a good practice [3–7].
A promising method for recovery is solid-phase ex-
traction with the use of polymeric sorbents , including
those obtained by the molecular imprinting technique.
Polymeric systems based on cyclic N-vinylamides are
highly effective in recovery of various classes of organic
compounds. Interest in these polymers is due to a broad
range of practically important properties they possess
[9, 10], which make them suitable for handling various
applied tasks, including those involved in sample prepa-
Here, we determined the regularities in recovery
of carbaryl and naphthols from aqueous and aqueous-
salt media by cross-linked polymers based on cyclic
N-vinylamides and developed a technique for their pre-
concentration from aqueous media.
We used 1- and 2-naphthol that were puriﬁ ed by sub-
limation and recrystallization from hexane, respectively,
using the known techniques  and identiﬁ ed them by
their melting points or molar absorption coefﬁ cients.
For preparation of solutions of carbaryl we used State
reference samples (7709-99).
As salting-out agents served chemically pure-grade
sodium, potassium, and ammonium chlorides and sulfates
recrystallized twice from bidistilled water.
The influence of surfactants on the efficiency of
recovery of the naphthols and carbaryl was estimated
