ABSTRACT Jackfruit (Artocarpus heterophyllus) is the largest known edible fruit which utilized parts are the bulb and seed while unutilized parts are the peels, core, and fibre. It weighs about 3.5-10kg and sometimes up to 25kg. The analysis of macro-mineral of jackfruit was carried out using Atomic Absorption Spectrophotometer. From the result, it was observed that jackfruit is composed of the following concentrations, calcium, (23.41±0.29mg/100g), sodium (7.53±0.51mg/100g), magnesium (2.41±0.48mg/100g), potassium (1.53±0.084mg/100g), and phosphorus (0.091±0.01mg/100g) respectively. From the result obtained, the…

ABSTRACT The inhibition of mild steel in 0.1M HCl solution using gravimetric method. The result obtained showed that alloxazine +KI is a good inhibitive of mild steel corrosion in HCl solution. The inhibition efficiency increased by 49% with increase in the inhibitor concentration of 10 x104MmKI. Physical absorption has been proposed for the absorption of the organic compound on the mild steel surface.   TABLE OF CONTENT PAGES TITLE PAGE        –         –         –         –         –         –         –         –         i CERTIFICATION…

ABSTRACT The levels of six trace metals namely iron, lead, copper, zinc and nickel were investigated in drinking water and ground water sources in Mbiaobong  village, ini L.G.A, Akwa Ibom State . Detected concentrations of Mn, Cu and Zn were below the world health organization and standard organization of Nigeria maximum permissible units. Fe (92%) and N1 (55%) in some drinking water and groundwater sources were found in concentration that exceeded the maximum permissible limits for these metals. Notably, the…

ABSTRACT The effect of Carica papaya extract of natural product for the prevention of corrosion inhibition of mild steel in acidic medium has been investigated. The study was carried out using the weight loss technique. The results obtained show Carica papaya leaves extract and potassium iodide as potential inhibitors of mild steel corrosion in H₂SO₄. the result revealed that the weight loss for the corrosion of mild steel coupons in H2SO4 decrease with increasing concentration of acid, rate of corrosion…

ABSTRACT The level of some heavy metals lead (Pb), cobalt (Co), nickel (Ni), cadmium (Cd) and Chromium (Cr) in wastewater sample collected from a fishpond located in Akwa Ibom State Polytechnic biological garden was determined using standard analytical procedures. The result revealed that the wastewater contained the analyzed heavy metals in the order Pb >Co> Cr >Cd>Ni. The concentration of some the metals analyzed were above the WHO recommended limit but nickel was below. Therefore, the wastewater can contaminate the…

ABSTRACT The concentration of trace metals in water from Abiakpo Ntak Inyang stream, Ikot Osurua, Ikot Ekpene, Akwa Ibom State, Nigeria were analyzed using atomic absorption spectrophotometer (AAS). The results of the analysis showed the concentration of the trace metals to be Fe (12.528  0.120 mg/l), Zn (4.186  120mg/l) Cd (1.880  0.004 mg/l), Ni (0.065  0.006 mg/l), Pb (0.240  0.035mg/l) and Cr (1.501  0.221 mg/l). The results also revealed that the concentration of the trace metals follow the trend Fe>…
