Abstract

This research aimed at determining the effect of chitosan in synthesizing imprinted Cu carbon-chitosan composite properties, the effect of imprinting Cu in carbon-chitosan composites to the adsorption efficiency and adsorption capacity of Cu in electroplating waste via batch methods, and the regeneration pattern of the composite. Composites were characterized using FTIR and SEM-EDX. In FTIR spectra, the addition of Cu caused the reduction of -OH and -NH functional groups intensity as the active site of Cu chemical bonding in 3448.72 cm-1. SEM-EDX analysis showed that the carbon-ionic imprinted chitosan composites after desorption contains the element of C = 60.17%, O = 38.8%, Cu = 0.83% and Na = 0.85%. The optimizations of Cu adsorption were studied from the concentration pattern of its variable, measured with Atomic Absorption Spectroscopy (AAS). The results showed that an optimum concentration for adsorption of Cu was 75 mg / L and an optimum contact time for adsorption of Cu was 24 hours with adsorption efficiency of 98.54% and adsorption capacity of 2.62 mg/g respectively. The adsorption yield of electroplating waste showed the adsorption efficiency of 31.62% and adsorption capacity of 367,79 mg/g respectively. Regeneration test was investigated from adsorption-recovery-reactivation (A-Rcov-RAct) steps. This regeneration test was carried out in three cycles. Recovery test was carried out using EDTA 0.05 M and 0.1 M HCl solutions. The efficiency of reactivation was identified from adsorption ability after activated with 0.1 M NaOH from two routes of recoveries. The results showed that recover agents do not influence the adsorption percentage, while to the recovery percentage progress, HCl 0.1M EDTA 0.05M. All routes of reactivation showed the similar results in average 99%

Abstract

Drainage is one way of removing unwanted excess water in an area and dealing with the effects of excess water in the system. When the rainy season comes, there are almost floods or puddles on urban roads. The large population also makes the volume of drainage channels fill up quickly, while the drainage capacity tends to decrease due to rainwater (erosion) and sedimentation. Meteorological Street, Laut Dendang Village, Percut Sei Tuan sub-district, Deli Serdang Regency, is one of the villages that is frequently flooded every time it rains. On these issues, the researcher highlights the importance of evaluating the Deli Serdang Regency's drainage system along Meteorological Road to anticipate when the rainy season comes. The general exponential method can determine whether the existing drainage volume can still accommodate terrestrial run-off and domestic wastewater in the next 30 years and calculate the population growth. Based on the research results from rainfall data obtained from Meteorology Road, the rainfall intensity value for the last ten years (2010 - 2019) was 10.538 mm/day. Thus, the amount of discharge flowing in the drainage channel (Qplansning) is equal to 0.832 m3/sec, while the planned Q for the next ten years is 0.874 m3/sec, for the next 20 years is 0.953 m3/sec, and 30 years into the future. front is 1.111 m3/sec. Based on the calculation results, Qplans exceeds Qeksisting. Therefore, a new channel plan is needed.
