Title: Development of Corncob-Based Biochar-Cellulosic Matrix for Heavy Metal Sequestration from Wastewater Authors: Ossamulu, I. F; Auta, H. S; Makun, H. A; Muhammad, H. K; Muhammad, H. L; Salubuyi, B. S Abstract: Freshwater contamination by heavy metals poses significant threats to human health and the ecosystem. This research explores the use of corncob-based biochar-cellulosic matrix for remediation of heavy metals from wastewater. Biochar-cellulosic composites were prepared in varying ratios (0:1, 1:2, 2:3, and 1:1) of biochar to cellulose. The physicochemical properties of wastewater and heavy metal (lead, copper, zinc, chromium and cadmium) quantification were determined using standard procedures. Acid hydrolysis and alkaline treatment was adopted for cellulose extraction while the biochar was produced through pyrolysis of corncob. The functional groups of the matrix were characterized using FTIR spectroscopy. The result showed that extraction of cellulose from corncob had a yielded of 33.65 %. Treatment of wastewater with the matrix resulted in significant improvements in water quality parameters, with reduction in turbidity from 423.0 NTU to 78.0 NTU, total dissolved solid (TDS) decreased from 60.6 to 35.5 mg/l, conductivity reduced from 49.2 to 39.3 nS/cm, while maintaining pH levels between 7.6-8.3 and temperature ranged between 28.0-29.5 °C. Wastewater treatment with the matrix also demonstrated significant reduction in heavy metal concentration. Lead decreased by 94.74 %, copper concentration was reduced by 58.33 %, zinc concentration decreased by 48.11-64.15 %. Furthermore, chromium concentration in wastewater reduced by 77.78 % while 42.86-85.71 % reduction was observed for cadmium. These findings demonstrated that corncob-based biochar-cellulosic matrix, particularly at a 1:1 ratio, offers a promising, sustainable solution for wastewater remediation, effectively removing heavy metals while improving overall water quality parameters.

Title: Effects of Pterocarpus Mildbraedii Extracts on Some Biochemical Parameters in Lead and Cadmium Chloride-Induced Toxicity in Rats Authors: Hamzah, R. U.; Busari, M. B.; Garba, R.; Hafsat, M.; Shem, Y. Abstract: The study evaluated the effects of crude extract and fractions of Pterocarpus mildbraedii leaf extract (PMLE) on kidney function biomarkers, haematological and antioxidant indices in lead and cadmium chloride induced toxicity in rats. crude extract (CE) of the leaf was obtained with methanol through cold maceration after 72 hours which was further subjected to solvent partitioning via vacuum liquid chromatographic (VLC) techniques using, acetone, ethyl acetate and 70% methanol Thirty-two wistar rats were divided into eight groups of four rats each comprising of the, normal, negative control, treatments and standard group. Exactly 10 mg/kg body weight (bw) and 50 mg/kg bw of cadmium and lead chloride was used to induced toxicity in rats. Administration of lead and cadmium chloride solution significantly (p>0.05) decrease super oxide dismutase, catalase activity, and glutathione concentration with an increase in the level of malondialdehyde in the negative group when compared with normal control. Likewise, administration of Pb/Cd Cl2 significantly (p > 0.05) increase the level of creatinine (Cr), urea, uric acid and sodium (Na) with concomitant decrease in potassium (K). Also, haematological parameters such haemoglobin concentration, packed-cell volume, red blood cells, total white blood cells, platelets, lymphocytes, mean cell haemoglobin, and mean cell hemoglobin concentration decreased significantly in the blood of negative control animals when compared with normal control. Treatment with crude Pterocarpus mildbraedii leaf extract and its fractions revert the antioxidants, kidney function and haematological alteration induced by lead and cadmium chloride toxicity in wistar rats with best activity in 400 mg/kg bw of acetone fraction and crude extracts. The crude Pterocarpus mildbraedii extracts have restorative effects on lead and cadmium chloride induced toxicity, thus, it can be use in the explored further for the management of lead and cadmium induced toxicity.
