Analysis of metal contents lead and cadmium in jamu asam urat using atomic absorption spectrophotometric has been done. The aim of this study is to analyze metal contents (lead and cadmium) in jamu asam urat with diffrent brands which are circulate in Padang cyti. Three samples of jamu asam urat with diffrent brands were analyzed the metal contents of lead and cadmium using atomic absorption spectrophotometric. The level of lead metal was obtained using regression equation y = 0.05378 + 0.02963x with R = 0.9977, and the level of cadmium metal was obtained using regression equation y = 0.08236 + 0.23186x with R = 0.9945. The result of this study showed that three samples were not detected containing metal cadmium, but three samples were positive containing metal lead, 2.2055 ppm (samples I), 3.6465 ppm (samples II), and 3.0156 ppm (samples III). The renits showed that all samples qualified for healy metal contamination by BPOM that less than 10 ppm for Pb and less than 0.3 ppm for Cd heavy

“…The human body only requires cobalt in small amounts. According to the Accept Daily Intake (ADI) tolerance limit, the human body requires 1000 μg/day of cobalt [3]. The cobalt ion has three unpaired electrons (d 7 ) so it can accept an electron pairs from the ligands to form complexes [4,5].…”

The complex of cobalt(II) with iso-nicotinamide (intmd) was synthesized at a 1:1 mole ratio of metal to ligand. The complex formula obtained is [Co(intmd)2(H2O)2]Cl2.nH2O (n = 0 or 1). The Co(II)-intmd complex was characterized by UV-Vis Spectrophotometer, Atomic Absorption Spectrophotometry (AAS), Differential Thermal Analyzer (DTA), Conductivity meter, Fourier-transform Infrared Spectroscopy (FTIR), Magnetic Susceptibility Balance (MSB), and Powder X-Ray Diffraction. Thermal analysis showed the complex contained several hydrates. The electrical conductivity of the complex in aquades is 1:1, the complex is electrolyte. The infrared spectrum shows that C=O and -NH2 from intmd are coordinated with metal ion. The electronic spectra show two peaks indicating the transitions 4T1g(F) → 4T1g(P) (ν3) and 4T1g(F) → 4A2g(F) (ν2). The complex is paramagnetic with μeff = 5.31-5.44 BM. It is suggested that the Co(II)-intmd complex has an octahedral geometry and an orthorhombic crystal system.

Currently, the electrochemical method as one of the fast, accurate, and reliable techniques for detecting heavy metals such as Co and Ni has been widely developed. Cyclic voltammetry methodology was successfully employed for determination of trace cobalt (Co) and nickel (Ni). Co and Ni levels are studied because they can cause water pollution and can be toxic, and non-biodegradable which influences the health of living things. To obtain results with high accuracy, this study tested several electrochemical parameters. Based on the results processed, the CoNi level in the solution can be measured well in the voltage range, scan rate, and pH of the solution, respectively, at -1.00 V to 0.75 V, 250 mV/s, and pH 3 (Ni) and pH 7 (Co). This work have been validated and showed good results with correlation coefficients of Co and Ni. The detection limit and quantity limit for Co and Ni were 510.2 ppm and 723.5 ppm, respectively, with 274.99 ppm and 916.66 ppm. Co and Ni metal RSDs also showed good values (<5%). In this study, Co and Ni levels in lab waste obtained by the cyclic voltammetry method were 510.2 ppm and 1666.47 ppm, and the results obtained from atomic absorption spectroscopy (AAS) measurements of 510.7 ppm and 1676 ppm. The developed electrochemical systems based are giving new inputs to the existing devices or leading to the development of novel heavy metal detection tools with interest for applications in fields such as environmental, safety, security controls or other industries.
