“…The details on the microsensor development were reported in [30]. Imaginary part of admittanse, S Frequency, Hz The optimal pH value, found here, corresponds well with the data reported by Karadag et al [31] and Vassileva and Voikova [32] where the authors show that pH value near to 6 provides high adsorption capacity of clinoptilolite toward ammonium. Thus, 5 mM phosphate buffer (KH 2 PO 4 -Na 2 HPO 4 ) with pH 6.0 was used further as a working solution for the clinoptilolite-based L-arginine biosensors.…”

Abstract. L-arginine conductometric biosensors were developed on the basis of arginase and urease cross-linked by glutaraldehyde in a single bioselective membrane and modified with clinoptilolite. The clinoptilolite intrinsic properties helpful for conductometric detection of L-arginine were investigated using three approaches to the creation of zeolite-containing enzymatic membranes. The developed biosensors were compared with the L-arginine biosensor, not modified with clinoptilolite, for the sensitivity, linear and dynamic range, detection limit, response time, operational and storage stability in L-arginine analysis. It was shown that the incorporation of ammonium-selective zeolite to the bioselective membrane of L-arginine biosensor allows increasing the biosensor sensitivity when applying all proposed approaches to the formation of zeolite-containing biomembranes. In addition, excellent values of both detection limit and linear range (1.0×10-5 M and 0.01-6 mM, respectively) were achieved for the biosensor based on arginase, urease and zeolite distributed in a single bioselective layer. The clinoptilolite-based biosensors for L-arginine demonstrated short response time, high operational stability (a coefficient of variations reached 0.74%), their lifetime exceeded four months.Keywords: L-arginine; Clinoptilolite; Conductometric biosensor; Arginase; Urease ЗАСТОСУВАННЯ АМОНІЙ-СЕЛЕКТИВНОГО ЦЕОЛІТУ ДЛЯ ПОКРАЩЕННЯ КОНДУКТОМЕТРИЧНОГО ДВОФЕРМЕНТНОГО БІОСЕНСОРА ДЛЯ ВИЗНАЧЕННЯАнотація. Розроблено кондуктометричні біосенсори для визначення L-аргініну на основі аргінази та уреази, іммобілізованих в одній біоселективній мембрані методом поперечного зшивання за допомогою глутарового альдегіду та модифікованій клиноптилолітом. Характерні властивості клиноптилоліту, корисні для кондуктометричного визначення L-аргініну, були до-слідженні за допомогою трьох підходів для створення цеоліт-вмісних ферментних мембран. Розроблені біосенсори порівнювали з біосенсором для визначення L-аргініну, який не був мо-дифікований клиноптилолітом, за такими показниками, як чутливість, лінійний і динамічний діапазон, нижня межа визначення, час відгуку, операційна стабільність і стабільність при збе-ріганні. Показано, що включення амоній-селективного цеоліту до складу біоселективної мемб-рани L-аргінінового біосенсора дозволяє підвищити чутливість біосенсора, застосовуючи всі запропоновані підходи для формування цеоліт-вмісних біомембран. Крім того було отримано чудові значення нижньої межі визначення та лінійного діапазону (1,0×10-5 М та 0,01-6 мМ від-повідно) у біосенсора, у якому аргіназа, уреаза та цеоліт були розподілені в єдиному біоселек-тивному шарі. Біосенсори для визначення L-аргініну на основі клиноптилоліту мали короткий час відгуку, високу операційну стабільність (коефіцієнт варіації досягав 0,74%), а їх стабіль-ність при зберіганні була вища за чотири місяці.

“…In fact, landfill leachate continues to be dangerous and poisonous over long periods, particularly for ammoniacal nitrogen that leads to stimulated algae growth, accelerated eutrophication, enhanced dissolved oxygen depletion and increased toxicity for living organism in water body (Aziz et al 2004;Karadag et al 2008). Consequently, it is vital to determine appropriate treatment method to cope with the changing quality and quantity of the leachate over times .…”

This study was carried out to investigate the treatability of ion exchange resin (Indion MB 6 SR) for the removal of chromium (VI), aluminium (III), zinc (II), copper (II), iron (II), and phosphate (PO 4 ) 3-, chemical oxygen demand (COD), ammonia nitrogen (NH 3 -N) and colour from semi-aerobic stabilized leachate by batch test. A range of ion exchange resin dosage was tested towards the removal efficiency of leachate parameters. It was observed that equilibrium data were best represented by the Langmuir model for metal ions and Freundlich was ideally fit for COD, NH 3 -N and colour. Intra particle diffusion model, pseudo first-order and pseudo second-order isotherm models were found ideally fit with correlation of the experimental data. The findings revealed that the models could describe the ion exchange kinetic behaviour efficiently, which further suggests comprehensive outlook for the future research in this field.

“…They also found that the loss of capacity of clinoptilolite after 10 regenerations in the sand filter with clinoptilolite where biological activity was enhanced was observed to be 10%. Karadag et al (2008) indicated that clinoptilolite could be used for ammonium removal from sanitary landfill leachate. The researchers also found that equilibrium was reached at 3 h and highest value of ammonium exchanged was 20.37 mg g -1 for the concentration of 3750 mg L -1…”

The important advantage of zeolite applied to water treatment is its high porosity when comparing to other minerals. The porosity results in good hydrodynamic properties (the increase in the pressure loss on the zeolite filters is 1.5-2.0 times smaller than in the case of sand filters) and adsorption roperties, and in turn high capacity which allows for adsorption of contaminants (a clinoptilolite filter allows for removal of phytoplankton and bacteria). The increase in the application of artificial fertilizers and gradual contamination of water resulted from discharging industrial wastewater into the environment led to the contamination of the environment by nitric compounds. Wastewater contains about 15-50 mg dm -3 of nitric compounds (based on nitrogen) -ammonia salts constitute about 55-60% whereas organic forms of proteins, pesticides and aminoacids about 40-50%. Natural clinoptilolite could be applied to remove ammonium ions from water and wastewater. The ammonium ion uptake behaviour of clinoptilolite is connected to the processes of ion exchange. The main aim of this investigation is to evaluate the adsorption capacity of clinoptilolite towards ammonium ions. According to the obtained results the adsorption capacity of clinoptilolite for the removal of ammonium ions demonstrates its potential application in the treatment of water, wastewater and sanitary landfill leachate contaminated with ammonia. The highest adsorption capacity of clinoptilolite towards ammonium ions of 3.79 mg g -1 was found for the initial concentration of 300 mg L -1 . The highest removal level reached by clinoptilolite for ammonium was of 99.74% for the initial concentration of ammonia of 50 mg L -1 . The effect of exposure time on maximum uptake of ammonia was found to be insignificant.
